How do I replace/reattach the front panel of my pants press?

I removed a screw at the bottom of the pants press thinking the legs will be detached, instead the entire front panel of the pants press came off. The parts that are available are: a screw, a concave shaved metal part which the screw goes thru, a slender round metal bar, and a flat shaped metal bar to hold up the front panel of the pants press. How do I put this panel back together?
