I need the code to be to if the cut equals none then custom I’m iprop is blank, like what I have written, but it keeps giving me an error ‘double’ with the code I have written

Hi, I ask you a question, the DIM parameter is numeric?
the parameters G_L1 and G_L2 are numeric?
if all are numeric you can not place in the value "" which is a text value of string, you must place the value zero. That's why the error message appears. regards

Is there a way to make it blank at all?
