Here you are setting a local variable visible only within
the saveas function. Tus the save function cannot see it.

You need to create the sbame variable outside the functions
and then declare it as global inside saveas.
This is all explained in my tuorial at:

As explained above the variables don't exist so you can't
compare them to anything yet!
