Just like to thank Bob Phillips, Bernie Deitrick and Ron de Bruin.
I've spent most of the day working on a nightmareish spreadsheet trying to
get it to work, and I couldn't have got it done without searching this
Discussion group and finding the bits of code I needed posted by these 3.
Since its date dependant will have to wait to see if it truely works
tomorrow, but it should.

A 4 meg file of "press this 1 button to do an hours work for you in 5
minutes" should hopefully be good :p
