VBA debug breakpoints

[Dan]

How can I get the VBA Editor to enter the true Debug mode
and allow breakpoints to be utilized?

I have done it with previous versions of Access (running
2003), I am attempting to just debug some code, yet
placing the breakpoints within the VB Code does nothing.
I can use my forms fine within access, but it never stops
within the VB code so I may debug the results.

Thanks for any assistance,

Dan
