SPANIM Help

Hey, guys. I would appreciate some help on getting my sprites animated with the SPANIM instruction. Basically I just want to know how to make it so I can press down on the D-pad and my character does a walking animation while moving. My code looks like this so far: [ SPSET 0,500:SPOFS 0,X,Y B=BUTTON() IF B AND #DOWN THEN Y=Y+1: SPANIM 0,60,48,144,60,64,144 ] However, when I use the SPANIM, my sprite gets stuck on the first frame rather than looping through the second one. I can't seem to figure out how to fix this so any feedback would be greatly appreciated. Thanks!

Forum protip: wrap your source code in code tags. (Quote my post to see the formatting source.) Secondly, you can make multiple-line IF statements in SB, so no more having to put it all on one line.

SPSET 0,500:SPOFS 0,X,Y
B=BUTTON()
IF B AND #DOWN THEN
 Y=Y+1
 SPANIM 0,60,48,144,60,64,144
ENDIF
