Message box on value

Hi all,

I need to trigger a message box if 2 conditions are met: A1>1 and A2>1 Message "Limit Exceeded".

On searching I've found some code but can't get it to work;

Option Explicit

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Column > 1 Then Exit Sub
If Target.Value > Target Then MsgBox _
"Please complete commentary section", vbCritical, "Input required"
End Sub

But can't get it to work. What is the "Target.Column" Refering to please ?
