The below formula entered nomally is supposed to lookup all values in Column
C which match 'Dallas' and concatenate the corresponding email address in Col
F. If you mean you are able to return only one mail address check out whether
the entries are 'Dallas' without any spaces or try out this in a fresh sheet
with some dummy entries

=VLOOKUP_CONCAT(C13:F500,"Dallas",4,"; ")

Sorry it toook so long to get back,
Hope you guys get this, but I have tyhe STRING CONCAT VBA installed
and it works great witha =STRINCONCAT(a1:a100,"; ")
you know it considates the whole range with ; in one cell

I copy and pasted the vlookup_concat VBA and no matter how I plug in the
the actual formula it will only produce one email address from the array
What I find strang is the email address it produces is actually the second
in series
=VLOOKUP_CONCAT(C13:F500,"Dallas",4,"; ")
is only producing one of the email address in specified range




So if all my office "names" are in col C and the email are in Col F
Say there is Dallas, Austin and Seatlle, 100 rows down, and F has ind. email
address
FYI Col C is sorted A-Z

=StringContcat(",",IF($C$13:$C$500="Katy",$F$12:$F $500,""))

this is the other suggestion with eith String concat, same result only one
email address,
and I did crtl shft enter too btw
please advise

These are the two VBA codes installed
Function VLOOKUP_CONCAT(rngRange As Range, _
strLookupValue As String, intColumn As Integer, _
Optional strDelimiter As String = " ")
Dim lngRow As Long
For lngRow = 1 To rngRange.Rows.Count
If CStr(rngRange(lngRow, 1)) = strLookupValue Then _
VLOOKUP_CONCAT = VLOOKUP_CONCAT & strDelimiter & _
rngRange(lngRow, intColumn)
Next
VLOOKUP_CONCAT = Mid(VLOOKUP_CONCAT, len(strDelimiter)+1)
End Function





You would need to add a new function to do this. Are you ok with using the
VBEditor?

Press Alt-F11
Click Insert Module
Paste in this code (sorry, it's a little long, be sure you get it all):

===========

===========

The code is also available he
http://www.cpearson.com/excel/stringconcatenation.aspx

Press Alt-Q to close the editor and save your sheet. You've just added a
function called StringConcat() to your sheet and it works very simply.

If your 1000 cells are range A1:A1000, use this formula in another cell:

=StringConcat(", ",A1:A1000)

Voila! Works like a charm. Will that work for you?
