Why do you need to use CallSub at all? Where is this sub declared?

Hello Erel and Don,
Thank you both for your replies!

@Don - I took a look at the sub and the calling line. I cannot see the problem.
@ Erel - I added a module called Text_Size. It is being called from the main module inside Activity_Create.

Actually until this occurred, I did not realize that using only "Call" or nothing would not work. Perhaps too many IDE's each with their own special syntax- and my assumption previously that this would be similar or the same. But somewhere I missed a whole bunch of important info it seems.

Thanks Erel - that makes complete sense! And a great indication of being too tired to try this out.
Thank you for your help!
