Strange (and soul destroying) RecordSet errors

I THINK this is a database problem...I am not sure.

I am basically trying to update my recordset...nothing more. I have done this hundreds of times but for some reason this one is throwing up the following error message when I call my update.

INVALID ARGUMENT VALUE

There is nothing unusual about the recordset (although I have converted it so that it is dynamic (Ie it uses different parameters and retrieves different fields dependant on what is needed at the time)) but this is something we deal with all the time.

If anyone has any thoughts on where and why this error is occuring I would be extremely grateful. It is probably something very simple but I have got blisters on my eyeballs from staring at this stupid code (I'm sure you chaps know the feeling).

Thank you for your time. Take care
