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
