Does Not Equal

edited 12/09/19 in Smartsheet Basics

I have a formula that is working for me....the last part of the formula includes if the "Partner Driven" box is checked. 

I now want to run the formula if "Partner Driven" is unchecked - I think it includes <> but I can't figure out where to include the "does not equal.

=COUNTIFS([Event Date]:[Event Date], <=Today(), Theater:Theater, "Americas", [Partner Driven]:[Partner Driven], 1)
