Multi-Field Formula to iterate through columns in data set

[tomek1988231]

Hi everyone, I need to create this workflow which allows to iterate through all columns in the data set and start some action if the coulmn name match from list (I can not select certain columns because I also iterate through diffrent columns form Data Base and deploy data into diffrent tabs). I think Multi Field Formula should do the job but I'm stuck on the expression, it seems it checks only first coulmn form the data. I've wrote something like this:

if _CurrentFieldName_ = IN( 'Col A', 'Col B', Col C')

then 'Red'

Else

_CurrentField_

EndIF

Can anyone advise?

somehow it works on my side, with a bit of modification.
