Be aware that if you have an OnFormat event it doesn't fire in Print Preview - and, just to be symmetrically a pain in the toches, the OnPrint event doesn't fire in Report View.
And... of COURSE in MicroPain's transfinite wisdom, you can't just copy the OnPrint routine to the OnFormat routine or vice-versa because they have different arguments.
This will be significant if you have a wizard build the report and you ask it to build summary totals in a given section footer.
