What happens if you remove the code you added to go against tblLoggedIn? Do
you get the correct data?

ok, I solved it.
Dim compid as string
compid = trim(rs.fields(0))
compid = left(compid, 12)
then I inserted compid into the WHERE clause instead of the the trim
command and the query worked. Now I have a new problem, lol. (I love
how solving one problem births more)
Now, when I run my form to show the computers connected to the
database I get the right number of records, but the records are being
duplicated. For example:
I have 4 people using the system but the code is returning only two of
the computer/username combinations and then duplicating them both
twice, so I have 4 records, but only 2 computers.
