AW: GUI Problem....

[etchekov]

Hi,

you should not call screen.clear() after creating the label... Thats why you can not see it - created and mikroseconds later destroyed (overdrawn) again.

very best regards

Emil

P.S. Just put screen.clear() directly after gui.destroy()...

uuuuuuy... yah, duh. I think I see what's going on. Thanks for the tip. I also forgot to put my end statement on my function, (although it's correct in the program, and of course wasn't the problem). So I've fixed that for your viewing pleasure.
