Is there away to have cell value add or delete copies of either cell ranges or worksheets without use of a button - excel

Question

I'm trying to make a cell value dictate how many copies should be made. I'm trying to make it if the cell value goes down that it will delete the sheets that are higher than the value. I currently have the adding working no problem just can't figure out how to make it delete copies when the value gets smaller. I figure I could make a button do a check just trying to make it more automated.
Sub CreateDistro()
Dim i As Long
Dim Num As Integer
Dim Name As String
Dim xActiveSheet As Worksheet
On Error Resume Next
Application.ScreenUpdating = False
Set ActiveSheet = ActiveSheet
Num = Range("C1")
If Num > 1 Then
For i = 1 To Num
Name = ActiveSheet.Name
xActiveSheet.Copy After:=ActiveWorkbook.Sheets(Name)
ActiveSheet.Name = "Distro-" & i
Next
End If
xActiveSheet.Activate
Application.ScreenUpdating = True
End Sub

Problem of the code below: it reacts on the Range("C1") of all sheets!
You might want to use a named range or limit the number of possible sheets(e.g. minimum number of sheets = 2, template to be copied is sheet 2,only sheet1 has the Worksheet_Change code.
Sheet1:
Option Explicit
Private Sub Worksheet_Change(ByVal target As Range)
Call ChangeSheets(target)
End Sub
Module1:
Option Explicit
Sub ChangeSheets(ByVal target As Range)
Dim iCt As Integer
Dim Num As Integer
Dim maxSh As Integer
'If Not Intersect(Target, Range("C1")) Is Nothing Then
' MsgBox ("C1: " & Target.Value)
'End If
If target.Value <= 0 Then
MsgBox "Minimum worksheet count = 1!" & vbCrLf & "Nothing to do!"
Application.EnableEvents = False
target.Value = 1
Application.EnableEvents = True
Application.DisplayAlerts = False
maxSh = Sheets.Count
For iCt = maxSh To 2 Step -1
Sheets(iCt).Delete
Next iCt
Application.DisplayAlerts = True
Exit Sub
End If
If Worksheets.Count = target.Value Then
MsgBox "Worksheet count = " & target.Value & vbCrLf & "Nothing to do!"
Exit Sub
End If
'add some sheets
If Worksheets.Count < target.Value Then
Num = target.Value - Worksheets.Count
For iCt = 1 To Num
ActiveSheet.Copy After:=Sheets(Sheets.Count)
Next iCt
Exit Sub
End If
'delete some sheets
If Worksheets.Count > target.Value Then
Num = Worksheets.Count - target.Value
Application.DisplayAlerts = False
maxSh = Sheets.Count
For iCt = 0 To Num - 1
Debug.Print maxSh - iCt; ": "; Sheets(maxSh - iCt).Name
Sheets(maxSh - iCt).Delete
Next iCt
Application.DisplayAlerts = True
Exit Sub
End If
End Sub
