I am trying to cut out the middle of this "P" graphic to make it transparent. I found tutorials on removing interior segments of objects using pathfinder, but every time I attempt to use "minus front" or "exclude," I get the error below ("images, gradient meshes, graphs, placed objects, and text paths cannot be used as compound shape elements"). I'm extremely frustrated and cannot find any solutions. Please help!
(I did locate some information indicating the graphic may be too small and should be somewhat expanded, but when I resized it, it gives the same error anyway. I also tried to use "expand appearance," but it was greyed out.)
