Use this:
exportwhatever = get(handles.("textboxname"),'string')
Put this code in the function callback. It will go to the text box and return in string format what is in the textbox.

I used the function above but I still get an error:
"Undefined variable "handles" or class "handles.text1". Text1 is the tag of my textbox. But, i do not understand how to access the handles from my textbox.
I tried
set(handles.text1, 'String', works);
where works is just a string. So, how do I get to recognize "handles" from my textbox in my button callback function

'Units','normalized','Position',[.4 .45 .2 .1]);
function pb_clbck(src,evnt)
