Detailed description of the Okay so I have been pulling my hair on this one for the entire day and I finally managed to reproduce the exact steps that this bug happens under! The problem arises in the AD&amp;D 2E Revised character sheet:&nbsp; <a href="https://github.com/Roll20/roll20-character-sheets/tree/master/AD%26D%202E%20Revised" rel="nofollow">https://github.com/Roll20/roll20-character-sheets/tree/master/AD%26D%202E%20Revised</a> , but could very well also be a problem in other character sheets! In the sheet there are two repeating sections: &lt;fieldset class="repeating_gear"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&lt;input type="text" name="attr_geardesc" &lt;/fielde &lt;fieldset class="repeating_gear-stored"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&lt;input type="text" name="attr_gear-stored-desc"&gt; &lt;/fieldset&gt; For each row to the&nbsp; gear-stored &nbsp;section, an invisible ghost row will confuse the index in the&nbsp; gear &nbsp;section. The nomral 'Add' button can be used. I also tested with a sheet worker with the following code: let newrowid = generateRowID(); let section = "gear-stored"; let field = "gear-stored-desc"; let newValue = {}; newValue[`repeating_${section}_${newrowid}_${field}`] = "test"; setAttrs(newValue); Minimum steps to reproduce the problem Steps to reproduce Have two repeating sections. In this case&nbsp; gear &nbsp;and&nbsp; gear-stored Use a sheet worker or the 'Add' button to create a new row in section&nbsp; gear-stored See that a row is created in the&nbsp; gear-stored &nbsp;section. Try to read the first value of the&nbsp; gear&nbsp; section&nbsp;using the chat command:&nbsp; @{selected|repeating_gear_$0_geardesc} Expected Get an error that field does not exist, similar to this: Actual Get an empty string as a value and print it in the chat: Note: If you delete the row in the gear-stored &nbsp;section then the invisible "ghost row" will also disappear from the gear &nbsp;section. I have setup a test game with a button that runs the above code and inserts the ghost rows:&nbsp; <a href="https://app.roll20.net/join/9451746/0amewg" rel="nofollow">https://app.roll20.net/join/9451746/0amewg</a> I have made a button, that is hooked up to the above mention sheet worker code for insert rows into the&nbsp; gear-stored &nbsp;section, for easier and faster testing. The same bug has also been tested with two other sections named&nbsp; weapons &nbsp;and&nbsp; weapons-damage , where the same behavior has been spotted. For each row in the&nbsp; weapons-damage &nbsp;section, an invisible "ghost row" will confuse the index of the weapons &nbsp;section. Description of setup Tested with the following browsers Google Chrome v. 83.0.4103.61 (Official Build) (64-bit) &nbsp; &nbsp; No Addons/Extensions (Clean install) Firefox v.&nbsp;84.0.1 (64-bit) &nbsp; &nbsp; No Addons/Extensions (Clean install) Microsoft Edge v. 87.0.664.66 (Official build) (64-bit) &nbsp; &nbsp; No Addons/Extensions (Clean install) Operating system Edition Windows 10 Pro Version 20H2 OS Build 19042.685 Experience Windows Feature Experience Pack 120.2212.551.0 Personally I think the problem is that the dash in the section name gets confused with the dash in the row id, and that is the culpit for the problem. I have however not been able to find any documentation saying that dashes are not allowed in repeating section names.

I made another minimal test game to ensure nothing in my own sheet was creating problems. I can still reproduce the bug in a sheet only containing the following code: &lt;div class="sheet-2colrow"&gt; &lt;div class="sheet-col"&gt; repeating_row &lt;fieldset class="repeating_row"&gt; &lt;input type="text" name="attr_name" title="repeating_row_$X_name"/&gt; &lt;/fieldset&gt; &lt;/div&gt; &lt;div class="sheet-col"&gt; repeating_row-dash &lt;fieldset class="repeating_row-dash"&gt; &lt;input type="text" name="attr_name" title="repeating_row-dash_$X_name" /&gt; &lt;/fieldset&gt; &lt;/div&gt; &lt;/div&gt; I made another test game with the bug visible here: Ghost rows minimal example

Found another example that introduces Ghost rows. Repeating section using numbers can also introduce it! The following code has replicated the problem: &lt;div class="sheet-2colrow"&gt; &lt;div class="sheet-col"&gt; repeating_row &lt;fieldset class="repeating_row"&gt; &lt;input type="text" name="attr_name" title="repeating_row_$X_name"/&gt; &lt;/fieldset&gt; &lt;/div&gt; &lt;div class="sheet-col"&gt; repeating_row2 &lt;fieldset class="repeating_row2"&gt; &lt;input type="text" name="attr_name" title="repeating_row2_$X_name" /&gt; &lt;/fieldset&gt; &lt;/div&gt; &lt;/div&gt;

Workaround for "ghost rows" messing with indexes: Step 1 - Find the rows that cause trouble: Use the following code to find all the rows that have problems: Should be index0: @{selected|repeating_weapons_$0_weaponname} Should be index1: @{selected|repeating_weapons_$1_weaponname} Should be index2: @{selected|repeating_weapons_$2_weaponname} ... Any row that comes back with an empty name is affected by a ghost row. See this images for an example output: Step 2 - Fix the order In order to "fix" the order of rows for a repeating sections, click ' Modifiy ' and moving the lowest rows to the top. Do that for all rows affected: Step 3 - Validate the indexes: Use the same code as before to validate the new indexes are correct: Should be index0: @{selected|repeating_weapons_$0_weaponname} Should be index1: @{selected|repeating_weapons_$1_weaponname} Should be index2: @{selected|repeating_weapons_$2_weaponname} ... I hope this helps anyone who experiences the problem with rows :)

Yes, I have added it to the helpdesk and they have replied: Peter B. said: Update: Roll20 has use the information in this post to created bug ticket for their internal Development team. Since they created the bug ticket, I haven't heard anymore from the help desk. So I guess it will be fixed "soon™"&nbsp; ¯\_(ツ)_/¯

Agreed! ∇ince said: Hi Peter, have you also reported this to the helpdesk ?&nbsp; Seems that the roll20 has stopped reading the Bug Reports &amp; Technical Issues forum... ;-( I sent the new information about numbers also creating "ghost rows", ie. repeating_row and repeating_row2 &nbsp;and help desk returned with the following email: Hi there, Thanks for providing this information. I'm adding it to the ticket I created previously. If there's anything else I can do for you please don't hesitate to let me know. With this I hope that the fix will be either more extensive/complete and maybe even "sooner™"!
