Solved: How to test formulas results?

[ValerieT]

Hello. My question is probably very basic: I am learning bymyself VBA and I am having trouble to work with the results of a formula.

example I've already used...
If WorksheetFunction.IsNA(Cells(Go, 20)) Then...

How to test the same way if a cell is blank or for example =6?

In this examples,
cells(Go,20) is either blank or contains a formula returning a text.
cells(Go,21) is either blank or contains a formula returning a value

To make it work, I had to first copy/paste as value the result of the formula calculation, but I am sure I could skip this step.

Thanks!

[VBA]While Go < Lignes
Go = Go + 1
If Cells(Go, 20) <> "" Then
If Cells(Go, 21) > 0 Then
....
Else
....
End If
ElseIf Cells(Go, 21) = Cells(Go,3) Then
....
Else
End If
