Ambiguous name detected: Worksheet_change - excel

Question

I'm attempting to add a second code to a single worksheet and keep getting the "Ambiguous name detected" error. Realise that I need to combine the two codes but having trouble doing so. here are the two codes, one below the other:
Private Sub Worksheet_Change(ByVal Target As Range)
'are changes made within answer range?
Set isect = Application.Intersect(Target, Range("Answers"))
If Not (isect Is Nothing) Then
For Each chng In Target.Cells
'Get row number
startY = Impact.Range("Answers").Row
targetY = chng.Row
row_offset = (targetY - startY) + 1
rating_type = Impact.Range("Impacts").Cells(row_offset, 1)
If rating_type = "Major / V.High" Then cols = 16711884
If rating_type = "Significant / High" Then cols = 255
If rating_type = "Important / Moderate" Then cols = 49407
If rating_type = "Minor / Low" Then cols = 5287936
If rating_type = "" Then cols = 16777215
Impact.Range("Ratings").Cells(row_offset, 1).Interior.Color = cols
Impact.Range("Impacts").Cells(row_offset, 1).Interior.Color = cols
Next chng
End If
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
' To Select Multiple Items from a Drop Down List in Excel
Dim Oldvalue As String
Dim Newvalue As String
Application.EnableEvents = True
On Error GoTo Exitsub
If Target.Address = "$C$2" Then
If Target.SpecialCells(xlCellTypeAllValidation) Is Nothing Then
GoTo Exitsub
Else: If Target.Value = "" Then GoTo Exitsub Else
Application.EnableEvents = False
Newvalue = Target.Value
Application.Undo
Oldvalue = Target.Value
If Oldvalue = "" Then
Target.Value = Newvalue
Else
If InStr(1, Oldvalue, Newvalue) = 0 Then
Target.Value = Oldvalue & ", " & Newvalue
Else:
Target.Value = Oldvalue
End If
End If
End If
End If
Application.EnableEvents = True
Exitsub:
Application.EnableEvents = True
End Sub
Was hoping someone knows how to combine the two in order to circumvent this error.
Thanks in advance!

Based on my comment, you can track changes in more than one range as shown in the below sample code.
Private Sub Worksheet_Change(ByVal Target As Range)
'Exit the sub if more than one cells are changed at the same time
If Target.CountLarge > 1 Then Exit Sub
'Disable the event so that if the code changes the cell content of any cell, the code is not triggered again
Application.EnableEvents = False
'Error handling to skip the code if an error occurs during the code execution and enable the events again
On Error GoTo ErrorHandling
'Change event code will be triggered if any cell in column A is changed
If Not Intersect(Target, Range("A:A")) Is Nothing Then
MsgBox "The content of a cell in colunm A has been changed."
'Change event code will be triggered if any cell in column C is changed
ElseIf Not Intersect(Target, Range("C:C")) Is Nothing Then
MsgBox "The content of a cell in colunm C has been changed."
'Change event code will be triggered if any cell in column E is changed
ElseIf Not Intersect(Target, Range("E:E")) Is Nothing Then
MsgBox "The content of a cell in colunm E has been changed."
End If
ErrorHandling:
Application.EnableEvents = True
End Sub
