This tripped me up and I was pulling out my hair for a while…

Note the == is used for evaluation of nominal values. I should have remembered but it been a long time.

Thanks for providing the column expressions examples!
Very helpful, indeed.

It would be very helpful though, if there would be a low code solution for the everyday business user, that would allow powerful if else statements with a possibility to do data operations afterwards (Math formula, string manipulation etc.)
