Absalom, thanks for the picture of the form. Aside from the change to S&WHF at the top and the payment and address information at the bottom it appears identical to the old form. I've just edited one of my old files to match.

FWIW I am using Office 2003 and Windows 7 so there shouldn't be compatibility issues with the new form. Plus Open Office should have been able to open it. *shrug* Whatever the problem is, I now have a form that I can use thanks to your help.
