Wiring in a new light please help!!!

I am doing a small remodeling job in my living room and am installing a light fixture where there never was one before. On the section of the room i tore out there were 2 recessed lights. I am using that wire as my hot. I ran a new line up to my attic, installed a box, and the light fixture. Everything is good except when i wire in the switch the fuse keeps blowing. Here is how i have it wired. From the existing "hot" line and the new line i ran i am connecting both blacks and both whites to the switch and also both grounds to the green screw on the switch. I know that i dont have the wires backwards because i already tried that. I also know that the light fixture is good because i bypassed the switch all together and the light worked fine. Am I using the wrong kind of switch? Please help. Thanks.

The switch interrupts the black wire going to the light. The neutral white wire is not switched. Hooking both black and white to a switch creates a dead short. You really need to read a book on basic house wiring such as Wiring Simplified from Home Depot.

In addition to Ray's comments, which I think is right on, from what you are telling us, you may have a 4 way switch, if it has 4 screws. You want a SPST toggle switch, and as Ray says, the neutral is never switched. Only the black is broken between the two screws on the switch. Buy the book. Read it, please.

Also the green wires cannot rely on the green screw on the switch to connect them. They must be mechanically joined together by something like a wire nut and then connected to the screw. This may require you to add a short pigtail to make this connection.

I agree with and reenforce the suggestion to read a book before proceeding. In fact, I'll suggest that you find three home wiring books and read all three cover to cover before doing anything else. A little knowledge is a dangerous thing.
