calling a frame's method

Hello all,

I have a bunch of frames on a main form. I keep track of the current
frame via a variable - say CurrentFrame. Now, after assigning frame1
to CurrentFrame, I would like to say something like
CurrentFrame.DoSomeInitializations, where the method
DoSomeInitializations are public procedures within each frame. Why
does this fail? How to correctly do this?

TIA
