Yeah I reckon I could do that ItsMe, but in all honesty I could run it without the OVERALL totals - it's probably the least significant of all of the totals that I need to calculate. The amount of time and effort that everyone is putting into it doesn't justify the outcome, so unless it's something you really want to see through to the end, I'd be happy to leave it out completely.
Creating date filters that I can embed into buttons is more of a priority for me now, though even that I can do manually if need be.
I'm starting to drown in data entry from this project, so I need to pick and choose how much time I put into the development of it!
Let me know if you're happy to let it go, or if you want to nut it out - either way thanks a heap for all your help ItsMe and June7!!
