Norman M. said: Hello - I am new to creating custom character sheets and have been learning lots on here. However I can't find anything about adding certain numbers on a character sheet together and having the total appear in another place. I am not sure for something so simple if I should learn to use the worker elements or if I should use the auto-calc feature, or if there is some better way to achieve this simple task. Thanks in advance for any help you can provide a n00b!! You can read more here: <a href="https://wiki.roll20.net/Building_Character_Sheets#Sheet_Workers_Scripts" rel="nofollow">https://wiki.roll20.net/Building_Character_Sheets#Sheet_Workers_Scripts</a> There are basically two ways: Auto-calc fields Sheet workers The general consensus is to use sheetworkers as they work in the background. This means while the worker is calculating a new value the user can still browse around the sheet. Auto-calc work in the UI thread, meaning while it is calculating the new value the sheet is blocked for user interaction. If you have few auto-calc fields then it will be nearly impossible to notice as they calculate quickly. If you have a lot and especially if you have auto-calc fields that calculate based on other auto-calc fields, then it will start to be slow.
