Hi,

Download and install the following addin -
http://www.download.com/Morefunc/300...-10423159.html. Thereafter you
may use the following array formula (Ctrl+Shift+Enter) in cell E5

=SUBSTITUTE(MCONCAT(IF(Sheet1!$B$4:$B$7=D5,Sheet1! C4:C7),","),",FALSE","")

B4:B7 of sheet1 has the project titles
C4:C7 of sheet 1 has the Roles
D5 of sheet2 has the project title

Can anyone figure out how to write a formula for the following
problem?

WORKSHEET 1:
Column A = Project Title
Column B = Role

Each project may have multiple rows if a staff member works on the
project in different roles.

WORKSHEET 2:

Concatenate role names found via conditional statement

Column A Column B

Project 1 Project Manager
Project 1 Developer
Project 2
Project 3 Business Anyalyst

I'd like to take any/all roles performed on a certain project and
concatenate them in a cell on another worksheet.
