Please carefully read this >LINK< and give your posts a meaningful title - 'Error while burning through avrdude' would have been good. Your situation may seem urgent... but actually it's only urgent to you.  :P

Back to your problem, you included your code, but there should be an error code and message from avrdude. That would be helpful in this case.

Also try adding the -v (verbose) option to your avrdude command to get more detailed feedback.

From what little I have learned so far with the programming thing, I don't see where the ATMega has been defined. I see where the CPU speed has been set to 1 MHz.
