Rebecca,
You have a much more severe problem than you even know. If you have so many
fields that you reached the 255 field maximum for a table (and have even
expanded to 4 tables), there are serious design issues with your database.
Continuing with this design will only create more headaches as time goes on.
You need to stop right now and rebuild it from scratch using the principles
of Normalization.
On my website ([URL="http://www.rogersaccesslibrary.com"]www.rogersaccesslibrary.com[/URL]), I have a Database Design
Tutorials section
([URL="http://www.rogersaccesslibrary.com/forum/forum_posts.asp?TID=238"]http://www.rogersaccesslibrary.com/forum/forum_posts.asp?TID=238[/URL]). There
are a few topics that explain Normalization and proper design, followed by
some tutorials that walk you through several projects. I strongly suggest
you take the time to learn the basics. It will save you mounds of work
later.
