Hi i have attempted to create a static GUI where i have five pushbuttons, where the user can select a respective section to place the gate. So far I was able to get it to work for one pushbutton but while attempting to add the other four pushbuttons, I was unsuccesful as only the 'AND' button is working. Can anyone advise on the code above to incoprorate the other four pusbuttons('OR','NOT','NAND'&'NOR') with the callback function selectionChanged.

[Spencer Chen]

I think the problem may lie in that you have nested your functions such that selectionChanged() is a nested function of AND1(). In which case, functions the same same level of AND1() has not access to it. You probably want to implement selectionChanged() at a higher hierarchy.
