Right - but checking purchase only just grays out the sell option. It's just cosmetically unnecessary and I was hoping to remove the whole thing.
But yes, this is the free demo version that I'm using.
Well, now it seems to be working. Not sure what the null was that tripped it before. But I'll grab the full version now!
Only other question I have is if there is a way to extend the section for the item name or allow it to drop down a layer? The item name, plus the price, plus the quantity ends up overlapping itself.
