drop down list

I need to create a sheet that has drop down menus on it. I was wondering if
there was a way to link the drop down list to another workbook, because there
are going to be several different workbooks that use the same menus. I would
like to have it so that i need to only change one instance of the list rather
than going into each file and changing the list in there.

This link should help
