How to tell that work explained in excel sheet is done in revit?

I have extracted data from excel file that states to draw a door and a wall of certain head height and length. I have also drawn these elements in Revit. Now I need a way to tell my user that work explained in excel sheet is done.
Can someone please tell me the code as == doesn’t help since we have two categories. any help will be appreciated

Hard to see what it is you are comparing. Perhaps try converting to a string as a first step.
