Empty values

I have an access database that has a field that could have nothing in it. (Blank). I am trying to set up a loop that will test to see if the value is blank. i.e.
Do While Not RecSetWip.EOF
        If (RecSetWip("WIP-Count").Value = Empty) Then
            WIPCount = WIPCount + 1
        Else
            WIP = WIP + RecSetWip("WIP-Count").Value
            WIPCount = WIPCount + 1
        End If
        RecSetWip.MoveNext
    Loop

I have tried NULL, Empty, "", but everything sets off the "Run time error 94, invalid use of NULL". How can I check to see if the value is a empty (blank) value?

Try using something like this.

Do While Not RecSetWip.EOF
If isNull((RecSetWip("WIP-Count")) Then
            WIPCount = WIPCount + 1
        Else
            WIP = WIP + RecSetWip("WIP-Count").Value
            WIPCount = WIPCount + 1
        End If
        RecSetWip.MoveNext
    Loop
