Executing if text reads 1 or more / Removing one from a number that is stored as text

Thanks for coming back to me. I’ve tried a few things and I’m not sure exactly how to do this. I can see why the way I’m deriving the count isn’t going to work. Duh.

I tried creating a variable that would hold the value of the items as an integer, but I don’t think I’ve done it right, as I can pick it up, but it doesn’t count up on the HUD.
