Hi Gozer, as a Pro subscriber you can use custom html and css to influence the sheet... in this case it looks like this is the area you'd want to edit (line 22): <input type="number" name="attr_xp_max" value="@{level}+7" disabled="true"> As you can see the calculation is level +7, easy enough to edit to whatever you want i reckon. The code is in the Roll20 github , grab it, change it in a basic text program and then add it to a 'custom' character sheet on your campaign settings page. If you want the value to be totally custom (editable) then remove the disabled="true" section which will allow you to overwrite any calculations... or remove the value too and it will just be blank until you enter a value for it :)
