Conditional Statements & Nested If/Then in VBA
I am trying to write a function or sub which passes in 3 variables from the worksheet and returns a number 0-3 based on conditional statements (nested If/then). However, the func returns ‘0’ for all cases. Using breaks in the module, I can see this is because, while the variables have been passed in (UpIso, Con, DIso), the function (isolation) =’empty’
My code is below. Any help is appreciated. Thanks
Code:
Function Isolation(UpIso, Con, DIso) As Variant
Dim Y As Variant
Dim N As Variant
Dim NA As Variant
Dim FD As Variant
Dim BP As Variant
Dim Station as Variant
'Free discharge
If (UpIso = Y And Con = FD And (DIso = Y Or DIso = NA)) Then
Isolation = 0
ElseIf (UpIso = N And Con = FD And (DIso = Y Or DIso = NA)) Then
Isolation = 3
'Back Pressure
ElseIf (UpIso = Y And Con = BP And DIso = Y) Then
Isolation = 0
ElseIf (UpIso = Y And Con = BP And DIso = N) Then
Isolation = 2
ElseIf (UpIso = Station And Con = BP And DIso = Y) Then
Isolation = 1
ElseIf (UpIso = Station And Con = BP And DIso = N) Then
Isolation = 2
ElseIf (UpIso = N And Con = BP And DIso = Y) Then
Isolation = 2
ElseIf (UpIso = N And Con = BP And DIso = N) Then
Isolation = 3
End If
End Function
