Hi Rocketman,
That did the trick. I am a bit slow, being a novice with the whole programming thing. I managed to get it to work with the second process. Sorry Tom, I have only just worked out what you were getting at.
Just a note for anyone else who is reading along. The Date Difference should actually be Day_Difference.
Cheers and thanks to all who have contributed. I am grateful for the continued support this forum offers. It makes my life a whole lot easier.
Regards
PM
