Thanks Martin,
Unfortunately this didn't work for me. But I found that the following worked:

SELECT Suspense.policyno, Suspense.claim, Suspense.drftamt,;
Suspense.dduedate, Suspense.claimname, Suspense.dol, Suspense.ssn,;
Suspense.adjustor, Suspense.clmoffice, Suspense.ntlogin,;
Suspense.controlnum, Suspense.susp_code, Suspense.den_code,;
Suspense.accepted, Suspense.denied;
FROM suspense;
WHERE Suspense.clmoffice IN ?param1,?param2,param3, etc..


Cheers,
