Gui pop up menu that i created is not having memory of the past selection...

eg: say popup has 2 options in the order: red blue

if the user has selected blue first time, then second time, since by default, popup shows red....user (who wants to now select red), leaves it untouched...but gui actually works with the memory of blue's selection...

I have tried some techniques to solve this but nothing seems to work.. Any suggestions....?

The popup will not automagically change from blue to red - you must have told it to in code, or the user changed it to red. It will not change by itself from blue (which the user just selected) to red.

If the GUI uses "blue" but the popup actually displays "red" then you're not getting the value of the popup when you need to use it. Get it like this

selectedItem = get(handles.popup1, 'Value');
