input link between token and custom sheet

I try to link an input (hit points and nonlethal damage ) in the sheet to the token, but I got a strange behavior  with a standard input no problem : <input name="attr_hit_points" type="number" value="" label="" /> <input name="attr_hit_points_max" type="number" value="" label="" /> but I had some difficulties with an input using calculated value, I tried this first : <input name="attr_hit_points" type="number" value="@{var1}+@{var2}" disabled="disabled" label="" /> <input name="attr_hit_points_max" type="number" value="@{var3}+@{var4}" disabled="disabled" label="" /> but with no succes at a point I have tried something like  : <input name="attr_hit_points" type="number" value="@{hit_points_base}" label="" /> <input name="attr_hit_points_max" type="number" value="@{hit_points_max_base}" label="" /> <input name="attr_hit_points_base" type="hidden" value="@{var1}+@{var2}" disabled="disabled" label="" /> <input name="attr_hit_points_max_base" type="hidden" value="@{var2}+@{var3}" disabled="disabled" label="" /> And now I got one token linked correctlty and the others don't ( in a same game ) I retried the previous point with no succes ; I am not able to repeat the manipulation :( for the records, the name contains some underscore but without I have the same issue some one got a similar situation ?

Firstly, you need to have "attr_" at the start of the attribute names so that they will be saved properly to the sheet: <a href="https://wiki.roll20.net/Building_Character_Sheets#Common_Mistakes" rel="nofollow">https://wiki.roll20.net/Building_Character_Sheets#Common_Mistakes</a> I'm not sure about the how the linking sheet stats to tokens by defaults is done, and your attempted process is unfamiliar to me, I think whatever you're attempting to do should likely be done in a completely different way. Someone else might know better.

damned I miss the attr_ prefix ( not in my game but here for the example, I change that ), thank you for the remark

I think there is a current bug where you cannot link autocalculated fields to tokens.

autocalc attributes have never worked great with token bars - especially since as soon as you edit them, it breaks the link with the sheet (since it doesnt match the calculation any more). If you want to link a calculated attribute to a token bar, you need to calculate it with a sheet worker. Iwas going to suggest a sheet worker to do this, then noticed your hit points and hp_max attributes are calculated differently: &nbsp; &nbsp;&lt;input name="attr_hit_points_base" type="hidden" value="@{var1}+@{var2}" disabled="disabled" label="" /&gt; &nbsp;&nbsp; &lt;input name="attr_hit_points_max_base" type="hidden" value="@{var2}+@{var3}" disabled="disabled" label="" /&gt; is that intentional? Also, i hope var1, var2, and var3 arent the actual names for these values. They should be something more descriptive, like "health" or "constitution".

@rabulias If it's a bug, And when I am sure I didn't make a code mistake, I will report this @GiGs for this example I simplified the code ( I sticking to xhtml as an habitude since years ^^ ) For further explications of my code, I code a Pathfinder sheet and I try to show in a header the current health ( hit-points, nonlethal damage, wound, vigor), the calcul are shown in the body. For hit-points in particular I have : hit_points = hit_points_base + hit_points_miscelleanous + hit_points_temporary + hit_points_status hit_points_max = hit_points_ceiling + hit_points_status all value are number inputs, exept hit_points_status is calculed with a ECMAscript function the code sample you give correspond to my second example, but it's dont work, so far : link a number input to a token work link a number input with attribute disabled to a token don't work link a hidden input with attribute disabled to a token don't work link a hidden input with attribute disabled link to a number input to a token don't work remove underscore in name don't change a bit remove the text/worker code change nothing I made some other test, I tried to link to the token some inputs : for number input with value="" it's ok ( ok with or without attributes min, max or step ) for text input (with number value ) it's&nbsp; work only on changing the bar variable ( not updated after that ) for number input with value calculated it's not working ( exept one time but I am not able to repeat that ) so a dirty solution is to use an number input with attribute readonly , link it to a token, and change the value with the a ECMAscript code
