Hello, I had this same issue. Collections need to be delt with differently in your sql. Try this: SELECT parameter from table Where $X{ IN, "Data Field" ,"YourParameterName"} In my case my sql is as follows: SELECT REMKL001."RKCTID" AS RKCTID, REMKL001."RKCUST" AS RKCUST, REMKL001."RKJOBN" AS RKJOBN, REMKL001."RKLINE" AS RKLINE, REMKL001."RKRQTY" AS RKRQTY, REMKL001."RKCODE" AS RKCODE, REMKL001."RKEMP1" AS RKEMP1, REMKL001."RKEMP2" AS RKEMP2, REMKL001."RKSUP" AS RKSUP, REMKL001."RKCRMK" AS RKCRMK, REMKL001."RKYRMK" AS RKYRMK, REMKL001."RKMRMK" AS RKMRMK, REMKL001."RKDRMK" AS RKDRMK, REMKL001."RKQTY" AS RKQTY, REMKL001."RKITEM" AS RKITEM, REMKL001."RKISFX" AS RKISFX, REMKL001."RKCOLR" AS RKCOLR, REMKL001."RKTNET" AS RKTNET, REMKL001."RKRNET" AS RKRNET, REMKL001."RKRGN" AS RKRGN, REMKL001."RKPO" AS RKPO, REMKL001."SUPNUM" AS SUPNUM, REMKL001."SUPNAM" AS SUPNAM, REMKL001."SUPCMT" AS SUPCMT, REMKL001."ENTDAT" AS ENTDAT FROM "XXXXXX"."REMKL001" REMKL001 WHERE $X{ IN ,RKCODE,RemakeCode} AND ENTDAT between $P{BeginDate} and $P{EndDate} AND $X{ IN, RKSUP,Supervisor} ORDER BY RKSUP ASC, RKCODE ASC Hope it helps
