Hi
You havn't specified the value of Fat when n = 1, so the code assumes
it is 0.
Try
Sub Test()
x = Fat(10)
MsgBox x
End Sub


Function Fat(n As Integer) As Long
If n < 1 Then Exit Function
If n = 1 Then
Fat = 1
Else
Fat = n * Fat(n - 1)
End If
End Function

You need the output value as long not integer or you will get an
overflow error.

Paul

I am currently working on. Here is my botched attempt.

Sub Test()
x = Fat(10)
Msgbox x
End Sub

Function Fat(n as Integer)
If n < 1 Then Exit Function
Fat = n * Fat(n-1)
End Function

Code returns 0 for any value of n.

TIA
