I hope someone out there can help me in an idiots guide sort of way.  I have a crosstab report that calculates number of bookings for an event based on date column and type of booking row.  I can get the weekly totals fine, and even a running total too for each cell - but if the total for one week/booking type is 0, the cell shows 0.  I need it to show previous week total (e.g. 10) plus current week (e.g. 15 if current week is 5, or 10 again if current week is 0).  Does that make sense? Can't believe I'm the only person to need this (I have seen a post elsewhere but don't understand the suggested fix).

Look forward to hearing of a really easy fix (fingers crossed).

Many thanks

Jules
