Struggling using the ChatSetAttr API | Temporary HPs

Hi all. Not sure what I'm doing wrong. I'm trying to script a macro that adds temporary HP when a player uses Fiendish Vigor in 5e.  Currently using the D&D 5E by Roll20 sheet for character sheets and the latest version of the ChatSetAttr script by Jakob. I get a "no target characters" error when I attempt to use either variants of the script shown below.  The script rolls the appropriate dice and shows the appropriate verbiage in the chat message.  It even adds a hp_temp attribute to the character selected, but does not change the temporary value on the main character sheet nor the attribute field. I tried this on HP as well and it gives the same error.  I'm running the script as a GM and I have the player token selected when running the script. Version 1 &{template:default} {{name=Fiendish Vigor}} !modattr --sel --hp_temp|[[1d4+4]]!!! {{Temporary HP=$[[0]]}} Version 2 &{template:default} {{name=Fiendish Vigor}} !modattr --sel --hp_temp|{{[[1d4+4]]=Temporary HP added to @{selected|token_name}!}}!!! I'm sure I'm just missing something simple :) -Pak

Do you have a token selected and does the selected toke "Represent" a character sheet in the token settings?

Hi Kraynic. Yes, a token is selected when running the script.  And just double checked that the token is indeed tied to a character sheet in the token settings.  It will even add a hp_temp attribute to the character sheet in question if it's (a) not on the sheet prior to running the macro or (b) the attribute was removed by me as a test to see if it would get added again.

The --sel targeting option doesn't seem to work too well with the CSA's !inline !!! commands. Try this instead: &{template:default} {{name=Fiendish Vigor}} !modattr --charid @{selected|character_id} --hp_temp|{{[[1d4+4]]=Temporary HP added to @{selected|token_name}!}}!!!

Hi Oosh.  Thanks so much for the suggestion! Version 2 of the script I was trying to run was actually a manipulated version of an older post that you recommended to another player :) At any rate, I used your suggestion posted above and got a new error: "Attribute hp_temp is not number-valued for character Lara Firahel. Attribute left unchanged" But I took the Version 1 script and applied your --charid trick and it WORKED!!! The final line I ended up using that worked for me is shown below: &{template:default} {{name=Fiendish Vigor}} !modattr --charid @{selected|character_id} --hp_temp|[[1d4+4]]!!! {{Temporary HP=$[[0]]}} I'm not sure why the Version 2 line interpreted "hp_temp" as a non-number value...? Nonetheless.  I TRULY appreciate the assistance as well as the original inspiration you provided with your older post. Cheers! -Pak
