Are you incrementing iPageCounter *both* when the frame is created and when it is called? The other place to watch is when you are assigning the name of the frame: I would suspect that page counter is not being incremented. 

The scope of the variable is important: so if you increment a variable in one subroutine/function it won't be incremented in the other unless either (a) it is declared outside of both functions, (b) it is passed from one function to the other. 

I think you should probably declare iPageCounter outside of both functions and use it within each. 
Dim iPageCounter 
Public Function... 

Fundamentally it is a matter of making sure that the textframes are labeled correctly and that they are called by the appropriate names.
