concatenate problem

Guest

I followed a link (in this forum) to the following code to concatenate
multiple fields onto one line, separated by commas. It works perfectly as
along as the field I'm trying to combine is a Number (double). The problem
is I am pulling this info from a third party database that can't be changed.
Even though the info in this particular field is numeric, it has a data type
of "text".

I won't be the one running the reports, so I need the code to combine the
based on a text field rather than numeric. The code is posted below. What
do I need to change to accomplish this? Thanks.

Function Concatenate(pstrSQL As String, _
Optional pstrDelim As String = ", ") _
As String

'Concatenate("SELECT FirstName FROM tblFamMem

Use syntax like:
FirstNames: Concatenate("SELECT FirstName FROM tblFamMem WHERE txtFamID =
""" & [txtFamID] & """")

Thank you SOOO much! You're a genius! I knew someone who knew what they
were doing could answer this in their sleep! Thanks again!
