Somehow you are deleting the figure that the button is attached to.

Search your code for the words "clear" and "delete" and make sure it makes sense, and is needed, to call them when you do. Changes are, you did "clear all" in the function which blew away the essential "handles" structure variable.

How did you create the interface: programmatically, using GUIDE, or using App Designer? Check the appropriate section on this documentation page for instruction on how to code your app's behavior. If you have your app open in GUIDE or App Designer, you should be able to edit the callbacks the same way you would add code to a new callback.
If you have opened your UI's code in GUIDE or App Designer and cannot edit the code in those environments, please say a little more about what "I can not" means: do you receive an error (and if so what's the full text, everything in red of that error?), do you receive a warning (ditto, except everything in orange), etc.?
