V024424 and V024425 should include values only for post-election cases selected for M11c (V024424) or M11d (V024425) administration in the post-election wave. Randomization values for M11c and M11d were assigned to all cases but were used only when M11c or M11d was assigned to a case. The following recode will remove codes for cases which should be INAP:

if V024423 in(2,3,4) then V024424=.;
if V024423 in(1,3,4) then V024425=.;
