Ok, that sounds like it could be a solution. Thanks for the tip. I am developing on Ac97, however the final product will be run on Ac2000, so I'll have to make my own function. I can set to doing this, but to save reinventing the wheel, if anyone out there has such a function already written, and is willing to share, could they point me in the right direction. If it's possible to do this, it would be great to have on which accepts multiple 'Find/ReplaceWith' pairs, so as to not need to repeat the function multiple times.

Many thanks,
