If you were to look at all the information you have, and present it on the forum, I think the answer will be obvious to you. Please try to be exact with your words. Null is not the same as blank. You’ve said it’s null, what var and type of var null and what are you trying to do with it? You need to be solving tiny problems like this yourself, using print statements, small test programs, the debugger. The forum is very inefficient for this.
