[quote]I think the problem might be due to "selection list".
If you just remove all those GUI element, then the code can not find the selected level so there is an error.
Find the name for the selection list ,and find code related to that name, replace with proper value/code.
Do you mean prof i delete this part from code [quote]Reset","Clear","level1","level2","level3 [/quote]
And after recompile again i do it but what deleted is text in buttons and choose option but buttons stay not deleted only minimum size of buttons.
I tried delete buttons totally to no appear but always give error when i recompile again.  :-\
