Type Mismatch in conditional

Question

I am new at VBA, but i have been programming a lot of C#. My issue here is that i keep getting "Runtime error 13. Type Mismatch" error in my VBA function.

I am extracting data from a Table in access and then trying to filter some of the data.

My function looks like this:

Function FlowType(deliveryAdrID As String, deliverType As String, note As String) As String
    If (note = "*J") Then
        FlowType = "Weekend"
    ElseIf (deliveryAdrID = "62242" & deliverType = "H") Then
        FlowType = "AirGotland"
    ElseIf (deliveryAdrID <> "62242" & deliverType = "H") Then
        FlowType = "Air"
    Else
        FlowType = "Standard"
    End If
End Function

Why do I get this error? The error occurs on this line:

ElseIf (deliveryAdrID = "62242" & deliverType = "H") Then

Answer 1

Your problem is because you use & , instead of And . The ampersand symbol is an operator to concatenate strings, whereas And is a Boolean operator. So, change your comparisons like so:

ElseIf ((deliveryAdrID = "62242") And (deliverType = "H")) Then

With & , (assuming both conditions are satisified) the expression you are using will evaluate to

ElseIf ("TrueTrue") Then

which doesn't make sense since "TrueTrue" is not Boolean.

Answer 2

You declare deliveryAdrID as Double, but you try to assign a String to it:

deliveryAdrID = "62242"

That's a Type Mismatch, as VBA tries to tell you. ;)

So, just use

deliveryAdrID = 62242
