Can I update a list from a table in access

[Bethylonian]

I have a form that uses a drop down menu to identify the companies that we
work with, is there any way to automatically update the original list table
from the main form without having to enter new company details more then once?

What's the Row Source of the combo box (where it gets its values)? What's the
Recordsource of the main form on which the combo is found?

 

[Bethylonian]

The row source of the combo box is "Company LookUp Table" and the record
source of the main form is "Coffey Phone Database"

Since I cannot see your database, have no idea what's in these tables or how
they're related, or what it is that you want to enter where, all I can say is
"consider using the Not In List event of the company lookup table to enter a
new company as appropriate".

For a more detailed answer... please post some more details.
