ERROR: WHERE clause operator requires compatible variables

hello I have my query below

What I'm trying to do is use the asmt_tmplt_id and restrict the data so that it only takes these 4 ids, I get the error below when I try, is it just the wrong type of statement I'm doing?

proc sort data=lib.fall_assessments out=tmp3 nodupkey  ;
     where BLD_ASMT_ID in ('461') ;
      by MBR_ID ARC_QUEST_ID RSPN_CHO_ID  ;
   proc sort data=tmp3 nodupkey ;
   where ASMT_TMPLT_ID in ('6746','6953','7086','7173');
      by MBR_ID ARC_QUEST_ID  ;
   proc transpose data=tmp3 out=tmp3 ;
     by MBR_ID  ;
     id ARC_QUEST_ID ;
     var RSPN_CHO_ID ;
   run ;

NOTE: There were 4468 observations read from the data set LIB.FALL_ASSESSMENTS.
      WHERE BLD_ASMT_ID='461';
NOTE: 106 observations with duplicate key values were deleted.

Apparently your ID variable is actually numeric and not character. Remove the ' from the IN values.
