Setting max HP using ChatSetAttr

I am trying to set up a macro to set HP automatically, using ChatSetAttr and the Shadowdark RPG sheet. Here's how the hp boxes look in the sheet code:                                         <label for="pc_hp_current" title="Hit Points">HP</label> <input type="text" class="sd-num" name="attr_hp" title="@{hp}" id="pc_hp_current" placeholder="HP"> <span>/</span> <input type="text" class="sd-num" name="attr_hp_max" title="@{hp_max}" id="pc_hp_max" placeholder="Max"> The macro appears to work correctly. This message pops up in chat: And the hp attribute is indeed set to 5. But it does not actually set hp_max to 5. A hp_max attribute appears with the correct value on the Attributes & Abilities tab, but the hp_max box on the sheet itself stubbornly refuses to change to anything other than 1. This isn't something specific to the way I wrote the rolls in the macro. Just using something like: !setattr --sel --hp_max|5 does the same thing. Can anyone see what I'm doing wrong?

Hi Jan K.,  Try this:  !setattr --sel --hp||5 The base attribute name is hp, not hp_max.  It can be a bit confusing because sometimes someone names things attribute_something else so it might be attribute_max.  But Roll20 also uses _max or |max as part of the basic structure for an attribute.  ChatSetAttr uses the following structure:  --attributename|current|max where |current is the value you want to place in current and |max is the value you want in max.

Perfect, thank you.
