Hi Experts,
I try to do a simple substation, but I always get the error (Invalid operation).
I would like to get the result 1,5 - 3= -1,5
But I have the feeling that 1,5 is not identified as a number.
The formula in column "Treshhold TBD" is like this
=IF([Dev Type]@row = "NM", "1,5", IF(OR([Dev Type]@row = "EM", [Dev Type]@row = "NT", [Dev Type]@row = "TN", [Dev Type]@row = "TD"), "7,5", ""))
How can I fix it? Thanks
