Subject:   A datastep question

I have a following datastep:

data xx; set yy; if dr in (1 2); if pa='Y'; if tr in ('1' '2' '3' '4' '5' )then delete; if tr in ('11' '12') and xp=2 then delete; lb=1; run;

I tried to short cut it as below, but some where I made the logic wrong, Can anyone please look at it and say where I might have made that mistake:

data xx; set yy; if (dr in (1 2) and pa='Y' and tr not in ('1' '2' '3' '4' '5' )and (tr not in ('11' '12') and xp ne 2)) then lb=1; run;

Thanks you so much
