Record Changes To Specific Cell

I'm working on a spreadsheet that has a counting number value on the cell L2 and a score on cell L4. These cells will be changed during the day, L2 always increasing, but not with a uniform increment. The interval between the changes also varies. Each time L2 changes, L4 may or not change. I'd like to keep the record of the changes on L2 and L4, each one in a row, together with the date and time when the changes where made to L2 and only add one new row if the L2 value has changed. The records should start from line 6 on...

See the attached file for more details. Currently I'm doing the updates to the record rows manually, I'd like to make it automatic every time the value of L2 is changed from the previous value to a new one.

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$L$2" Then
If IsNumeric(Target) Then
'Stop any possible runtime errors and halting code
On Error Resume Next
'Turn off ALL events so the Target * 2 does not _
put the code into a loop.
Application.EnableEvents = False............
