column A- name of sales representative
column B - customer ID
(Not sorted in any particular order. So, a sales rep could be listed in row
5, 27, etc)

Sheet B ('Sales Rep Lists'):

Bill,
use the following array formula (Shift+Ctrl+Enter) in A2 of Sheet B:

=IF(ISERROR(SMALL(IF('Sheet
A'!$A$2:$A$100=$A$1,ROW($A$2:$A$100)),ROW()-ROW($A$2)+1)),"",INDEX('Sheet
A'!$B$2:$B$100,SMALL(IF('Sheet
A'!$A$2:$A$100=$A$1,ROW($A$2:$A$100)),ROW()-ROW($A$2)+1)))
