Hi! If you want to add the values of multiple columns together in a repeater, then you can expand on the OnItemLoad case to add values from multiple columns to either a global variable (like in this post) or to the text on the target widget (like in josephxbrick’s post). Here’s what that would look like in the “Edit Value” dialog if you add the values of two columns (Column0 and Column1) together and store them in a global variable, which you then use to set text on your “all sum” widget:
Hopefully that helps a bit!
