Also, which sheet are we talking about? I'm the author of the Tabbed sheet, but I know there are others out there. A few trouble shooting steps: Make sure you are using Chrome or FirefoxYou Make sure that all the fields have an actual value (0 and not blank, etc) Is the syntax error available only when using the roll template? (Assuming you are using the tabbed sheet, you can switch between using the Roll Template and not using a template via the Configuration section of the character sheet—black gear icon in the upper left-hand corner) If none of that makes a difference, what is the exact syntax error message you are getting? If it's only one game where you are experiencing this problem and not in other games using the same sheet, we may need to open a Trouble Report in the appropriate forum, because it may have to do with the actual game itself (just another thought).
