Worksheet Change error

Hello,

I am using this code:

Private Sub Worksheet_Change(ByVal Target As Range)
If ActiveSheet.Range("$G$60").Value = ("$T$5") Then
ActiveSheet.Range("$G$62").Value = ("$T$5")
Else: Range("$G$62").Validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:=xlBetween, Formula1:="=Level1Answers"
.IgnoreBlank = True
.InCellDropdown = True
.InputTitle = ""
.ErrorTitle = ""
.InputMessage = ""
.ErrorMessage = ""
.ShowInput = True
.ShowError = True
End If
End Sub

And I getting a invalid use of property error, highlighting the first line of the code.

I have tried a number of times but as my VBA knowledge is limited, i have hit a brick wall.
