Solved Where is wrong in this small query?

[Ashfaque]

I am fetching up some records in a subform thru a query:

SELECT T_JobOffer.CNo, T_JobOffer.CDept, T_JobOffer.CName, T_JobOffer.CLastWorkingDate
FROM T_JobOffer
WHERE (((T_JobOffer.CNo)<>IsEmpty("Cno")) AND ((T_JobOffer.CDept)=[forms]![F_SaudizationPercent]![TxtDeptEmp]) AND ((T_JobOffer.CLastWorkingDate)<>IsMissing([CLastWorkingDate])));

It is working properly and producing list of employees who has left the company because their CLastWorkingDate is entered.

But when I want those who are currently present in the company means their CLastWorkingDate is null, it is not working. It tried just removing <> that I mentioned before IsMissing([CLastWorkingDate]) condition.

Is there any other way?

It solved...I just tried with "Is Null" and not used IsNull which appeares in SQL design and worked...

Thanks,
