error A45 undefined symbol (pass 2)

i am makinga 4x4 keypad interacing program where da character pressed has to be sent serially to anothr board..
checking all 4 coulumns for each row,
i gave a an exit command

jb col4 exit

where da exit subroutine was written at da end
fisrt it gave me an error (TARGET OUT OF REACH)
THEN, realizing jb doesnt hav long enough range, i changed it to

jb col4 JUMP
JUMP: acall exit

now its giving an error "UNDEFINED SYMBOL (PASS 2)

tell me what to do? i have to make it jump only if my "jb col4" condition is fulfilled

    still it doesnt mean that i cant program in assembly...

    'da" and "the"
