I have a cell that populates by determining if the columns next to it have an
"X" entered. If they do, the name of the column is concatenated to the
current text, followed by a comma. If there is no "X", no text is added. I
use the formula below:

=CONCATENATE(IF(E3="X",$E$2&", ","")&IF(F3="X",$F$2&",
","")&IF(G3="X",$G$2&", ","")&IF(H3="X",$H$2&", ","")&IF(I3="X",$I$2&",
","")&IF(J3="X",$J$2&", ","")& etc...

This has woked fine for awhile, but now we have too many columns and the
formula is too long.

Any suggestions on how to make this work with a shorter formula?

Thanks in advance.
