How can I write this logic?

Constrain Self.Color.red of actor to tableCellValue(Table1, something, 1)

In Something what I need is to attach this value to:

Every 10 days row=row+1 until day 100 is reach
@day 101 the count starts over again and row = 1

I know it has something to do with ceil & Mod but I can't seem to figure it out.
