In VBA, the best way to debug a user defined function (UDF) is by writing a temporary Sub procedure that calls your function and then step into the Sub procedure by pressing F8 key.
Example :
Let's say you have the following function. This function calculates a grade based on the values of these scores. It takes two parameters: "score" and "score1".
Function grade(score As Single, score1 As Single) As String
If score >= 75 And score1 >= 75 Then
grade = "A"
ElseIf score > 50 And score1 > 50 Then
grade = "B"
Else
grade = "C"
End If
End Function
You create a Sub procedure within the same module where your function is defined. This Sub procedure will call your UDF with specific inputs. By using a Sub procedure, you can easily run and debug your function.
Sub test()
MsgBox grade(Range("A2").Value, Range("B2").Value)
End Sub
Position your cursor before Sub test() and then press F8 key to step into the Sub Procedure.

Perfect and simple solution. Thanks. Gary
ReplyDeleteThanks - this was helpful!
ReplyDeleteThanks. It works.
ReplyDeleteStepping into my function as described works, but calling it from the spreadsheet throws a #Name? error. Confused on why it would work if I step into it but not when I call it from a cell?
