What exactly are you asking? You made 2 loops already. It doesn't go to @loop2 because The GOTO says to go back to the @loop1 label before it can go to loop2. My suggestion? Do this:
@ULTRALOOP
Gosub @loop1
gosub @loop2
wait 1
goto @ULTRALOOP
Then replace the goto @loop1 or 2 with RETURN.
You don't,Put both loops in the same loop. So if I wanted it to constantly count up from 10 and count down from 10 then you would put U=0+1 D=10-1 goto @Loop instead of having a @Loop1 and @Loop2
