VBA Loop error (Creating NCCA BRACKET)

I got this great code through Experts Exchange and it works good except I have ran into a problem.  My friend and I are trying to build a NCAA bracket.   We use data validation to create lists as you move forward to each round of the bracket.  For example after you have selected teams for the round of 32 then only those teams can be selected for Sweet 16 and so on.   In an early question to experts exchange was how we could write code so that if someone selected a team in round of 32, then sweet 16, and say elite 8, but decided that actually that team would lose in the Sweet 16 then it clears that team out of future rounds since it is not longer an option and avoid mistakes.   This code works great on the left hand side of the bracket but it clears out the field of 64 on the right side of the bracket and freezes up.  Not sure how to change this to make it work.  I have uploaded the code as well as the worksheet to look at.  I am hoping to get this figured out today if anyone has time to help out.  
Private Sub Worksheet_Change(ByVal Target As Range)
Dim cl As Range, i As Long, strTeam As String

If Not Intersect(Target, Range("D6:N38")) Is Nothing Then
    Application.EnableEvents = False
        For i = Target.Column + 1 To 9
            strTeam = Target.Offset(, i - Target.Column).MergeArea.Cells(1, 1)
            
            For Each cl In Target.Offset(, i - Target.Column).MergeArea.Cells
                If cl.Offset(, -1) = strTeam Then GoTo noIssueLeft
            Next
            
            Target.Offset(, i - Target.Column).MergeArea.ClearContents

noIssueLeft:
        Next i
        
        For i = Target.Column + 1 To 9 Step -1
            strTeam = Target.Offset(, i - Target.Column).MergeArea.Cells(1, 1)
            
            For Each cl In Target.Offset(, i - Target.Column).MergeArea.Cells
                If cl.Offset(, 1) = strTeam Then GoTo noIssueLeft
            Next
        
            Target.Offset(, i - Target.Column).MergeArea.ClearContents
noIssueRight:
        Next i
        
    Application.EnableEvents = True
End If

End Sub

Hi, here is the code you need:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim cl As Range, i As Long, strTeam As String

If Not Intersect(Target, Range("D6:N38")) Is Nothing Then
    Application.EnableEvents = False
        For i = Target.Column + 1 To 9
            strTeam = Target.Offset(, i - Target.Column).MergeArea.Cells(1, 1)
            
            For Each cl In Target.Offset(, i - Target.Column).MergeArea.Cells
                If cl.Offset(, -1) = strTeam Then GoTo noIssueLeft
            Next
            
            Target.Offset(, i - Target.Column).MergeArea.ClearContents

noIssueLeft:
        Next i
        
        For i = Target.Column - 1 To 9 Step -1
            'get current selected winner
            strTeam = Target.Offset(, -(Target.Column - i)).MergeArea.Cells(1, 1)
            
            For Each cl In Target.Offset(, -(Target.Column - i)).MergeArea.Cells
                If cl.Offset(, 1) = strTeam Then GoTo noIssueRight
            Next
        
            Target.Offset(, -(Target.Column - i)).MergeArea.ClearContents
noIssueRight:
        Next i
        
    Application.EnableEvents = True
End If

End Sub

One final thing that I need help with.  If you want to start over and you select all cells or all cells with in a bracket and delete you get an error.  Any way to fix this?
