Oh well, I just made the window close on pressing the "confirm "
button.
That'll do!

Thanks again for all your help

Technically it could be, if the OP had done the following before creating
their handles structure:

figure(200)

but I agree with you that maxRecharge, maxDischarge, cellNum, and
batteryCapacity look suspiciously large to be figure handles, and figures
(and the root object which ALWAYS has handle 0) are generally the only
graphics objects that get integer-valued handles.

correct...
however, i looked at his/her code and (in a later post) referred to the command

handles.batteryCapacity = str2double(get(hObject, 'String'));

which clearly shows that the field's val cannot be a handle...

Reading ahead in the story, eh? Isn't that cheating? *grin*
