Sorry, its data validation. I forgot to add in the formula that I currently have, which should help clarify things a bit.

=IF(A9="Wellness",Sheet3!B6,IF(A9="TDS",Sheet3!B16,IF(A9="Healthy Back Non-Incentive",Sheet3!B25,IF(A9="Healthy Back Incentive",Sheet3!B34,IF(A9="Open",HELP,"")))))
I need help at the very end of the formula, where it says IF(A9="Open",HELP,....

I want to be able to freely enter whatever values I want when the "Open" selection is chosen.

Hope this helps, and thanks for the quick response!
