[RESOLVED] If ... AND ... then problems

So Ive set up a simple if else if statement with an "Or" and a "AND" operator.

vb Code:

Set TempRange = Blad2.Range(BoutMBegin, BoutMEind)
    For Each Cell In TempRange
        If Cell.Value = b_grade Then
            Blad2.Range(BoutMBegin).Select
            ActiveCell.Offset(-1, 1).Select
            bma = 0
            bmd = 0
            bmi = 1
            Do While Not IsEmpty(ActiveCell)
                If ActiveCell.Value = TempO Or TempA Then
                    If ActiveCell.Value = TempO And TempA Then
                        bma = bmi
                        bmd = bmi
                        Marr(3) = Cell.Offset(0, bma).Value 'Sa
                        Marr(7) = Cell.Offset(0, bmd).Value 'Sb
                        Exit Do
                    ElseIf ActiveCell.Value = TempO Then
                        bmd = bmi
                        Marr(7) = Cell.Offset(0, bmd).Value 'Sb
                        If Not bma = 0 And bmd = 0 Then Exit Do
                    ElseIf ActiveCell.Value = TempA Then
                        bma = bmi
                        Marr(3) = Cell.Offset(0, bma).Value 'Sa
                        If Not bma = 0 And bmd = 0 Then Exit Do
                    End If
                End If
                    If IsEmpty(ActiveCell) Then
            msg = "De ingevoerde waarde temperatuur is niet gevonden bij de boutmaterialen. Druk op ignore als u verder wilt gaan met de hoogst gevonden temperatuur."
            hdr = "Temperatuur niet gevonden"
            FDBCK = MsgBox(msg, vbAbortRetryIgnore Or vbInformation Or vbDefaultButton3, hdr)
            Select Case FDBCK
                Case 3
                    Exit Function
                Case 4
                    GoTo Retry_Bmat
                Case 5
                    If ITd = 0 And ITa = 0 Then
                        ITd = ITc
                        ITa = ITc
                        TempO = ActiveCell.Offset(0, -1).Value
                        TempA = ActiveCell.Offset(0, -1).Value
                    ElseIf ITd = 0 Then
                        ITd = ITc
                        TempO = ActiveCell.Offset(0, -1).Value
                    ElseIf ITa = 0 Then
                        ITa = ITc
                        TempA = ActiveCell.Offset(0, -1).Value
                    End If
                End Select
                Exit For
            End If
            bmi = bmi + 1
            ActiveCell.Offset(0, 1).Select
            Loop
            Exit For
        End If
Next Cell

This is the part where things go wrong:

vb Code:

Do While Not IsEmpty(ActiveCell)
                If ActiveCell.Value = TempO Or TempA Then
                    If ActiveCell.Value = TempO And TempA Then

Even if the value of the activecell isnt equall to TempO or TempA it still proceeds as if the value was. Then if the value is equall to either TempO or TempA it is also continueing through the second "If" statement and executing the code it contains.

Why? what am I doing wrong?

the OR should only work if one of the is equalls are true or both of them, and the AND should only work if both of them are true... right?

Try changing to:

If ActiveCell.Value = TempO Or ActiveCell.Value = TempA Then....

Just to be clear, this sort of statement runs as follows:

IF (evaluation to True or False) OR (evaluation to True or False) THEN ...


so you are saying:

IF (ActiveCell.Value = TempO) OR (TempA) THEN .....


Now, (ActiveCell.Value = TempO) can be evaluated exactly as it is, whereas there are no evaluative criteria for (TempA). Hence Excel will just evaluate TempA to be TRUE if it is something, and FALSE if it is nothing. Hence having any value for TempA will return TRUE in the evaluation, and hence the observed behaviour.
To correct it, you need to tell your code to perform a second evaluation, as suggested above.

Aah, yeah now I see where it went wrong...

Well Ill rewrite that part, and then it should work like a charm!

Thanks!
