You have a seesaw with 2 people on each end. the seesaw is on a pivot. label the forces in a free body diagram acting on the seesaw. Its online and I tried a force down on each end but then the pivot it keeps saying is wrong. I tried a force up from the pivot, a moment, force down, everything.

One force down at each end, and a force up at the pivot equal to the sum of the two end forces should be all you need in the free body diagram.
