I am learning how to go through assembly and I am running into a weird problem. I am getting a message stating,
collect2: error: ld returned 1 exit status
and before I get this message though I am getting a string of errors like this.

I am at a complete loss. I'll post my code below, I am hoping it is just one small error.
