In what way doesn't it work? Does your computer explode?

Here you set UserGmail and PassGmail to the contents of some text edits:

Judging by the names, I'd guess that they are strings.

Here your check whether they are 0, which is a number:

>           if PassGmail==0 or UserGmail==0 or UserSymbol==0 or UserStockPrice==0 or (RadioButtonAbove==0 and RadioButtonBellow==0):

Strings aren't numbers, and numbers aren't strings. "0" != 0.

Here you've indented the line more than the def Mbox, so this line is 
inside the function:

You're not calling it.
