i really need help to fix this interface , the last button also does not save image , why?

This line:
filename('waad s.jpg')
is not a valid code to put into MATLAB. I am not sure what you're trying to do, but this can fix it:
filename=('waad s.jpg')
I am not sure why you have that line in it (You should remove it). In your button, you're basically opening a picture, showing it in the GUI, and then saving it with a different name? Why is that?

You need to create a filename, then save it. You're not using the equal sign and not passing the filename into imwrite, which you should use since I've never heard of imsave().
fullFileName= fullfile(pwd, 'waad s.jpg');
imwrite(x, fullFileName);
You should also pick more descriptive variable names than single letters like x, something like grayImage, or rgbImage would be better and let your code be more maintainable by others.

filename('waad s.jpg')
sorry this line is mistake
what i want to do is saving the image displayed from this button
function pushbutton5_Callback(hObject, eventdata, handles)
by using saving button which is this one
function pushbutton6_Callback(hObject, eventdata, handles)
and i tryed to use it
is it wrong?
please i need help really
and is this only mistake in the interface?

That could be fine. I just never use imsave(). It looks like a combination of uiputfile() and imwrite() and acts upon the image in the current axes. So get rid of the filename line and it should work.
