#Error on a report

I'm getting #Error on a report.  Here is the control for the text field...

=DLookUp("[Initials]","tblEmployees","[EmployeeID] = " & [Reports]![rptTaskCard].[Report].[subrptTaskCardDetails]![cboMech])

How do I hide the #Error if there is no value in the DLookup?

Try

=IIF(ISERROR(DLookUp("[Initials]","tblEmployees","[EmployeeID] = " & [Reports]![rptTaskCard].[Report].[subrptTaskCardDetails]![cboMech])),"",DLookUp("[Initials]","tblEmployees","[EmployeeID] = " & [Reports]![rptTaskCard].[Report].[subrptTaskCardDetails]![cboMech]))

First suggestion still gave me #Error.

2nd suggestion did work.

That's because IIf() evaluates both the true expression and the false expression before determining which one to use. Thus it cannot be used in situations like this.
