Trying to get The Aarons' script working but nothing I do seems to get it going. Here are the details for my config: Version: Latest Authors: The Aaron User Customization Options Bar: Bar 1 Select the bar to use for hitpoints. Sheet: DnD 5e - OGL by roll20 Select the character sheet you are using to attempt to preconfigure for that sheet. HitDice Attribute: Type the name of the attribute used to store the HitDice formula. SRD Embedded Formula: Select this checkbox if the HitDice attribute has formula in the SRD embedded format '12 (3d4+5)' Separate Constitution Modifier: Select this checkbox if you store the constitution modifier separately from the HitDice formula. Constitution Attribute: Type the name of the attribute used to store the constitution value. Constitution is Stat: Select this checkbox if the Constitution attribute should be converted to a modifier ((CON-10)/2). I have also tried changing it to custom and using the HitDice Attribute as npc_hpformula Still no joy. Here is the sheet set up: Issuing the !mhd command results in: (From ): Rolling hit dice for 3 token(s). (From ): Rolling hit dice for 4 token(s). (From ): Rolling hit dice for 1 token(s). But no change to the tokens on the play area that are selected. I have also tried for 0.3.7 to see if it was an issue with the latest version and that hasn't worked either. Here is a list of the other scripts I currently have set up and running: EasyExperience GroupInitiative BloodiedDead.js TurnMarker.js Torch TokenMod hazInsipiration.js exportTable.js InspirationManager.js Rollable Table Macros Roll20 Audio Master splitArgs Vector Math Path Math MatrixMath HTML Builder Areas of Eff MonsterHitDice
