This command works fine and return 8 records

SELECT Request.iid, Request.dtoday, Request.dtois, Request.creqfrom,;
Request.creqdeptt, Request.creqdesc, Request.dneeded, Request.csubmtedby,;
Request.ccomplby, Request.dcompltd, Request.cstatus;
FROM isapp!request;
where Request.cstatus IN ('Testing', 'UnAssigned', 'In Progress')


where as this should return the same value but returns blank recordset

vp_cStatusField = "' Testing ', "+" ' UnAssigned ', "+" ' In Progress '"
?vp_cStatusField


SELECT Request.iid, Request.dtoday, Request.dtois, Request.creqfrom,;
Request.creqdeptt, Request.creqdesc, Request.dneeded, Request.csubmtedby,;
Request.ccomplby, Request.dcompltd, Request.cstatus;
FROM isapp!request;
where Request.cstatus IN (?vp_cStatusField)
