how come my line 339 doesn't work?

You want to change = to ==. Also, what is "(BUTTON(0)==#UP)==0" supposed to do? If you want to test if it's not equal to #UP, do "BUTTON(0)!=#UP". Or did you mean to use "AND" instead of the first ==?

To clarify, flarn2006 means your "IF...NUMB9A=27 AND NUMB9B=13" should be IF...NUMB9A==27 AND NUMB9B==13. The "THEN NUMB9A=23:NUMB9B=13" part is fine. Always think "IF something EQUALS something, THEN let something BE something." EQUALS is ==, BE is =. I also don't know what the #UP part is. What happens in your game when we press UP, and when we don't?

its a slide puzzle. trying to move emty space(number9) up

i've shortened but gives me same syntax error

here is progress that's not working

here is prpgress. line 339 shows an empty box

it works now. i have a favor to ask you guys:know a way to manipulate the coordinates without putting lots of if for each place. example instead of doing numb9ab goes up,left,right,down,next in line moves opposite.i need the one that moves up,left,down,right, next in line moves opposite without changing value
