That is perfect, thank you!

This form will likely only ever have one module (Module1), plus the individual worksheet modules and ThisWorkbook. I don't envisage the need to add any new 'functions' to this form after adding this administration page - perhaps the odd new button, but nothing as major as this. As for the 'redundant' code - that is basically unedited from where I got it from (shown in the code comments) as I don't like messing with things I don't fully understand more than necessary.

That said, I might step back and have another think about the layout of the admin page. At the moment it is designed mainly so that it all fits on one screen, but there is no real reason why scroll=bad (just my own personal preferences). Perhaps somethign to run past my colleagues.

Thanks again for all your help.
