Solved Run-time error '3077' Syntax error (missing operator) in expression.

[5hadow]

I have Run-time error '3077' Syntax error (missing operator) in expression error come up when trying to .findFirst in my recordset.

 'Criteria'
 strCrit = "pkEventID = " & DMax("pkEventID", "tblEvents", "[fkAircraftID] = " & Me.cboTail & " AND [fldDateEnd] is null")

'Part of code'
                .FindFirst strCrit
                If .NoMatch Then
                    Resume Next
                End If

It works ok when there are matching records. However, when it's a new record I get the error. I expect it not to find a record, but I don't want the error.

Does anyone know what's wrong with syntax? I also tried this:
strCrit = "pkEventID = " & DMax("pkEventID", "tblEvents", "[fkAircraftID] = " & Me.cboTail & " AND [fldDateEnd] is null") & ""

maybe put Nz():

strCrit = "pkEventID = " & Nz(DMax("pkEventID", "tblEvents", "[fkAircraftID] = " & Nz(Me.cboTail, 0) & " AND [fldDateEnd] is null"), 0) & ""

Add a debug.print strcrit to see what it resolves to.

is [fkAircraftID] numeric?

maybe put Nz():

strCrit = "pkEventID = " & Nz(DMax("pkEventID", "tblEvents", "[fkAircraftID] = " & Nz(Me.cboTail, 0) & " AND [fldDateEnd] is null"), 0) & ""

That works, thanks!
