Rebuild Error help with Revolve

Hey there,

I'm really new with SolidWorks so I'm sorry if this is a silly question...

I have been tasked with creating a coke can. I would have thought the easy way to do this would be to extrude a circle but my teacher wanted me to do it by sketching the cross section of the front and then revolving it.

So I've spent the afternoon sketching it but now when it comes to revolving it, no matter what I try it always comes up with the Rebuild Error: "Unable to make a revolution with the given profile. The profile may be self intersecting".

I have attached my file of what I have done, can anyone tell me how to fix this issue?

Thanks
