Special Division Formula in webforms
Hello,
I'm building a new form in Planning, and I want to make a division of a cell by another cell. For this, I'm trying to use *Mod* function in Formula member column. For example, I need to divide the cell C2 by C1. So, I wrote the next formula :
GridName.GridElement[cell(C2)].property, GridName.GridElement[cell(C1)].property
and it looks like this :
But when I click to validate I have this error message :
This formula is invalid: Encountered " <COL_ID> "GridElement "" at line 1, column 10. Was expecting one of: "row" ... <COLUMN> ... "cell" ... "[" ... "cell" ... "[" ... "[" ... "[" ...
Which thing is wrong in my actions ? Could you please help me ?
