MIPS jump loop - high order error -

i cannot seem right reason, googled bunch too, not find solution this. getting error:"target of jump differs in high-order 4 bits instruction pc 0x400054". tried jump in increment of 2 jumps reach goal, still not work. doing wrong? trying jump loop: section.. there way can this?
