I am designing a shroud for some lights on the grill car. I've drawn up everything, and the last thing I need to do is bend the piece to fit the curvature of the grill. I am trying to use the deform tool, but I am having trouble picking the initial curve. Every time I click the edge of the object, and try to deform I get "no body is selected". Every tutorial I have looked at has not really helped.

I am still learning the ropes of Solidworks, so does anyone know what I need to do get the deform tool to work. The part is also attatched below.
