How do I solve the error: Undefined variable "handles" or class "handles.edit21"?

I have developed a GUI.When the pushbuttton is clicked, the calculation is done and the calculated number which is stored in the variable 'T' must be displayed in an edit box as the output. I have used
set(handles.edit21,'String',T);
in the pushbutton callback. However when i click the pushbutton, I get the following error:
Undefined variable "handles" or class "handles.edit21".
How can I rectify this?

Variable 'T' should be converted to string using num2str(T) first, before calling. Have you done this?

Whne the variable handles is unknown, you have to define it. This is actually trivial, so I'm not sure what the problem exactly is. A guess:
handles = guidata(hObject);

Did you use any clear -command family in your GUIDE code?
Such as:
clear
clearvars
clear all
