Update a global when going to a stack as modal

[Sarah Reichelt]

Are you sure you are declaring gFoo as a global in BOTH places?
If you forget the "global gFoo" line in the script of stack B, then it 
won't change the value of the real global, just a local variable of the 
same name.

Similarly, if you don't have the global declaration in stack A, then it 
will be using a local variable which will not be affected by setting a 
global of the same name in stack B.

Cheers,
Sarah
