ActiveSheet_Change is not automatically executing commands

Hello,

Quick question:

The following code DOES work BUT I have to go into VBA and run the command manually for the If statement change to actually execute.


What I want is for this to execute automatically, meaning that If A13 = "Test" Then I want it to automatically execute the Next line whereby the Cell A14 will change its value to "Done". What am I missing in this code here?

Thanks in advance

Private Sub ActiveSheet_Change()

If Range("A13").Value = "Test" Then
   Range("A13").Offset(1, 0).Value = "Done"

End If

End Sub
