Try this in place of your current $remove line:

Code:
$gettok($gettok($remove($wildtok(%t,*BF2:11*,1,32) $+ $remove($gettok(%t,$+($calc($findtok(%t,$wildtok(%t,*BF2:11*,1,32),1,32) + 1),-,$calc($findtok(%t,$wildtok(%t,*BF2:11*,1,32),1,32) + 16)),32),$chr(32)),:),2,41),1,40)


It should work for all situations:

(BF2:11) 01 02 ...
(BF2:11)01 02 ...
(BF2:11): 01 02 ...
(BF2:11):01 02 ...
