Crash due to invalid program counter

So my question is how do i fix this error. Is it the structure of my program? or how i went about using the registers?

I think the problem is you are not linking your jump to red.

Change j red to jal red on line 23

Change addi $t0, $zero, 1000 to addi $t0, $t0, 1000 on line 34 to add 1000 to $t0 and store it.
