G'day there Peter T,

If the routine is in a normal module in the same and in the same workbook as
the change event there should be no problem to call it from the event code.

That's what I thought too. It's good to know that I haven't completely
lost the plot :)

Put a break in the event on the line that calls the routine.

I'll have to leave it this morning. I shan't have much time to do
anything fun until later this evening.

Hopefully I'll be able to see what's going on.

Thanks for your assistance,
