Re: [MS_AccessPros] DLookup question



Well first, DateDiff is a horrible way to calculate someone's actual age or years of service.  That merely extracts the Year portion of both dates and subtracts.  The correct way to do it is:

DateDiff("yyyy", [DOB], Date())+ Int( Format(Date(), "mmdd") < Format( [DOB], "mmdd") )

The second one is close.  Why did you remove the quotes around Jim Wagner?  Try this:

=DLookUp("[Employees Years of Service]","qryYearsOfService","FullName = 'Jim Wagner'")

I am trying to do a dlookup on a form and have come to a head and a wall. I have a query Named qryYearsOfService. The query calculates the years of service. But the form gave me a #Name? error so I tried it another way and the next expression gave me an gets a #Error error. I must be missing something so simple here. Any help will be of great assistance to me. 

Thank You

 SELECT tblInformation.FullName, tblInformation.DOB, DateDiff("yyyy",[tblInformation]![DOB],Now()) AS [Age of Employee], tblInformation.YearsOfServiceDate, DateDiff("yyyy",[tblInformation]![YearsOfServiceDate],Now()) AS [Years Worked], [Age of Employee]+[Years Worked] AS [Employees Years of Service]

FROM tblInformation;

On the form I have several text boxes that neither work.  

Text Boxes on form

this onea #Name? error

 =DLookUp(["Employees Years of Service"]!["qryYearsOfService"],"FullName = 'Jim Wagner'") 

This one gets a #Error error
=DLookUp("[Employees Years of Service]","qryYearsOfService","FullName = Jim Wagner")
