Format Range when cell value entered - excel

Question

I have a template where the user enters account information and the default range for information is range B18 to S52. This fits nicely onto the screen and is a big enough range for the details being entered 90% of the time. However on a few occasions the use may have data that is a few hundred rows. Its usally copied and pasted in but would make the sheet look messy as it would be out of the default range.
I'm trying make the formatting dynamic where by if the user enters data outside of the default range a macro is triggered that will count the rows and reformat the range.
The code I have so far from researching online is:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$B$18" Then
Call CountLoc
End If
End Sub
Public Sub CountLoc()
With Application
.DisplayAlerts = False
'.Calculation = xlManual
.EnableEvents = False
.ScreenUpdating = False
End With
Dim LocCount As Long
Dim WsInput As Worksheet
Dim i As Long
Dim rng As Range
Set WsInput = Sheets("Account Input")
With WsInput
LocCount = .Range("B1048576").End(xlUp).row - 17
End With
If LocCount > 35 Then
Set rng = WsInput.Range(WsInput.Cells(18, 2), WsInput.Cells(17 + LocCount, 19))
With rng
.Interior.Color = RGB(220, 230, 241)
.Borders.LineStyle = xlContinuous
.Borders.Color = vbBlack
.Borders.Weight = xlThin
End With
For i = 1 To LocCount Step 2
Rows(18 + i).EntireRow.Interior.Color = vbWhite
Next i
Else
Exit Sub
End If
This essentially colors every other row light blue and white and adds a border to each cell. The Count Loc works fine and does what I need it to do but the problem I have is that I cannot get the worksheet_Change to trigger.
Thanks in advance

there
I ran a little test using your code and the first thing I noticed, is that you set the Application.EnableEvents to False and you don't set it back on, so you are cancelling any event like the Worksheet_Change Event once that's fix the event will trigger any time the cell B18 changes, except if the value that is entered comes from a paste(not sure why) but if you use the Intersect method then it works even if the value came from a copy paste.
I did some small tweeks to your code and I think it works now. please review it and give it a try.
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, ThisWorkbook.Sheets("Account Input").Range("B18")) Is Nothing Then
Call CountLoc
End If
End Sub
Public Sub CountLoc()
Dim LocCount As Long
Dim WsInput As Worksheet
Dim i As Long
Dim rng As Range
Set WsInput = Sheets("Account Input")
With WsInput
LocCount = .Cells(.Rows.Count, "B").End(xlUp).Row
End With
If LocCount > 35 Then
Set rng = WsInput.Range(WsInput.Cells(18, 2), WsInput.Cells(LocCount, 19))
With rng
.Interior.Color = RGB(220, 230, 241)
.Borders.LineStyle = xlContinuous
.Borders.Color = vbBlack
.Borders.Weight = xlThin
End With
For i = 18 To LocCount Step 2
Set rng = WsInput.Range(WsInput.Cells(i, 2), WsInput.Cells(i, 19))
rng.Interior.Color = vbWhite
Next i
Else
Exit Sub
End If
End Sub
