Checkboxes that allow multiple boxes to be checked, stored as a string?

Hey, guys! I have an issue with pesky check boxes I am trying to resolve (pardon my ignorance, here; I'm kind of feeling my way through how things work). If you set a checkbox with an "attr_" value that is the same for all the input, they will swap out just like a radio button (so you can't have two of them checked at the same time). Not the behavior I want. I want them to be able to have multiple boxes checked at the same time. This can be easily accomplished with a DIFFERENT name on each checkbox's attribute name (e.g., attr_checkbox01, attr_checkbox02, etc.). But this makes a separate attribute for EVERY checkbox (Ack!). Not what I want either. What I need is a way to add the value to a single string value attribute that includes every box checked (such as "1, 7, 28" indicating that checkbox 1, 7 and 28 are checked). I have a strong feeling there is a DUH answer for this. But my searches have not turned up anything. Any suggestions.

There's not a duh option, you'll need to do a sheetworker with this, something that detects when something is changed so that it can grab the appropriate attributes and combine them.  <input readonly input="text" name="attr_combined"> <input type="checkbox" name="attr_part1" value="This">This <input type="checkbox" name="attr_part2" value="Is A">Is A <input type="checkbox" name="attr_part3" value="Test">Test <script type="text/worker"> on("change:part1 change:part2 change:part3 sheet:opened", function() {     getAttrs(["part1", "part2", "part3"], function(values) {         let operation = values.part1 + values.part2 + values.part3;         setAttrs({             "combined": operation         });     }); });      </script>

Ugh. Well, guess I've got my work cut out for me. Thanks, Brian! Richard T. said: There's not a duh option, you'll need to do a sheetworker with this, something that detects when something is changed so that it can grab the appropriate attributes and combine them.

I am not sure if this will help or not but you might check out Kurt J's scriptcards which offers the ability to set up arrays.&nbsp; This would allow each item to be loaded separately yet manipulated into and out of a single string variable at need.&nbsp;&nbsp;

Thanks, Michael! That could prove useful!

Awesome! That will probably be helpful for the next guy/gal! I parused that page and a tone of others looking for a solution. 👍 Andreas J. said: Added the example to the wiki: <a href="https://wiki.roll20.net/Sheet_Worker_Snippets#Summing_up_values_based_on_multiple_checkboxes" rel="nofollow">https://wiki.roll20.net/Sheet_Worker_Snippets#Summing_up_values_based_on_multiple_checkboxes</a>
