GUI throws error: Attempt to reference field of non-structure array.

I have a simple GUI made from GUIDE. it throws me this error: Attempt to reference field of non-structure array.

I have a editbox and a button. When I click on the button, the system will get whatever input is in the editbox.

I have searched it in google, where the reason of throwing this exception is overwrote original handle structure . But I'm sure I never overwritten anything. Previously the code was working, but after a week I get back to the code, it starts to throw the exception.

You are probably trying to use,

 handles.something

where you have not previously defined it in the callback function or if it is your user variable, you haven't not defined in the opening function.

Posting your code will help us trap and obliterate the bug :D
