Hello everyone. I'm working on one project and I have this problem: i need to set text for static text object. Lets say its name is text1 and after pushing a button it should say "this is requested text".
code:

function pushbutton1_Callback(hObject, eventdata, handles)
.....
....
....
set(handles.text1,'String','this is requested text')

but it prints this error: 
??? Reference to a cleared variable handles.
Error in ==> projekt_final>pushbutton1_Callback at 102
set(handles.text1,'String','this is requested text')

I'm not using text1 anywhere else in project.
Strange thing is that I was doing the same thing in my previous project and it worked. I'm really desperate, pls help. Thank in advance, Miloš.

Are you sure you didn't add a 'clear' command somewhere in the Callback ?

I've noticed a fair number of people routinely tossing on clear and clear all 
statements in functions... never been able to figure out why.
