hi, Art !

does a udf serves well ? (i.e.)

Function ConcatenateIF(cond As String, comp As Range, conc As Range, _
Optional sep As String = ", ", _
Optional match As Boolean = False, _
Optional skip_blanks As Boolean = False) As String
Dim criteria As Range, n As Integer, match1 As Boolean, tmp As String
tmp = ""
For Each criteria In comp
n = n + 1
match1 = IIf(match, criteria = cond, LCase(criteria) = LCase(cond))
If skip_blanks Then match1 = match1 And Not IsEmpty(conc.Cells(n))
If match1 Then tmp = tmp & IIf(Len(tmp), sep, "") & conc.Cells(n)
Next
ConcatenateIF = tmp
End Function

use it as any integrated ws.function (i.e.)

- sheet 2:
[B1] yellow
[H1] =ConcatenateIF(b1,sheet1!b2:b6,sheet1!a2:a6)

hth,
hector.

__ OP __
Is it possible to search a column in one sheet for all occurrences of a search item
and then put the result of that search in a single cell on a second sheet?
For example, Sheet 1 may have something like this:
A :: B
John yellow
Mary yellow
Sue red
Richard green
Michael yellow
In the second sheet, I have a row for each color, and I want to put in, say, H1
the names in Sheet 1 that have that color in column B.
C :: H
yellow John, Mary, Michael
So, say I have "yellow" in B1, I want the spreadsheet to put in H1 the name of each person in Column A
separated with a comma and space, in Sheet 1 who has that color in Column B.
It's possible there may be NO occurences, ONE occurence, or MORE THAN ONE occurence
which makes it even more difficult because I only need commas/spaces for MORE THAN ONE occurence.
Thanks!!!!
