Trying to pass a parameter to procedure but getting an exception thrown?

I would like to pass an 'inputCounter' parameter by pushing it onto the stack. Within the procedure, I dereferenced the stack pointer pointing to this parameter, and would like to add it to the address of array and then increment it by 4 (size of the array) However, I am getting an error of:

Exception thrown at 0x00403729 in Project.exe: 0xC0000005: Access violation writing location 0x0080C0ED.

I am using Visual Studio and the irvine32.inc library.

I've tried debugging ebx (the register I hold my inputCounter in) and in the first run through I expect it to be 0 and then the second run, I expect it to be 4. However, it starts at 0 (which was defined in my main) but then it jumps to '0040607B' for some reason. And the error occurs with the line:

mov [esi], eax.

Help would be much appreciated!
