simple oop question (hopefully)

[Eric_Dexter at msn.com]

I am just trying to acess a function in wordgrid (savefile) to a button
that is defined in TestFrame.  I can't seem to make it work I either
get an error that my variable isn't global or it makes other
complaints.  thanks in advance..  sorry for the simple question..
