You're supposed to copy the function from the bottom of that page (between
the 2nd and 3rd hortizontal lines) into a new module. Make sure you don't
name the module ELookup: Modules cannot be named the same as functions or
subs contained within them.

ELookup() is not a built-in function.
You need to copy the code from:
http://allenbrowne.com/ser-42.html
and paste it into a module in your database (i.e. click the Modules tab of
the Database window, click New, paste the code, and save the module with a
name such as "Module1".)
ELookup() has just been updated to handle multi-valued fields in Access
2007. It returns a concatenated list of the key values (as DLookup() does.)
It still works with earlier versions, of course.

Thank you Allen and Douglas.
This makes complete sense now.
I appreciate your quick response.
