def FindLabel ( [INSERTEDMAINSIZE], [INSERTEDMAINMATERIAL] ):
return str([INSERTEDMAINSIZE]) + " " + str([INSERTEDMAINMATERIAL])
I'm using ArcMap 10.2. There are null values in [INSERTEDMAINSIZE] and [INSERTEDMAINMATERIAL]. Instead of labeling the Null values as "None" I don't want them to show up on the map at all. If there is a value for that features, I want that to label, just not the null values. How do I add this to the script?
