VBA Worksheet_Change event for multiple worksheets

[Lil Stinker]

I'm using the following code to add, copy, edit client info from my client table stored on Sheet3 to my main form on Sheet1. It works great for these purposes. However, now I want to implement the same functionality for another worksheet with different range results while still pulling from the same client table worksheet.

I've tried using the same code and changing the ranges accordingly but it doesn't run correctly on Sheet2. No errors come up. It just doesn't recognize the client and wants me to add them again. How would I go about achieving the same result I get from Sheet1 on Sheet2?

Apologies if the code is inefficient, I'm new to VBA. Appreciate any help you can provide.

Private Sub Worksheet_Change(ByVal Target As Range)

If Not Intersect(Target, Range("C13")) Is Nothing And Range("C13").Value <> Empty Then
    Dim projROW As Long
    If Range("N2").Value <> Empty Then 'project exists
        Sheet4.Range("M1").Value = "EDIT"
        ActiveSheet.Shapes("EDITPRObttn").Visible = msoCTrue
        projROW = Range("N2").Value 'project id
        Range("B5").Value = Sheet3.Range("D" & projROW).Value 'billing address 1
        Range("B6").Value = Sheet3.Range("E" & projROW).Value 'billing address 2
        Range("B7").Value = Sheet3.Range("F" & projROW).Value 'billing address 3
        Range("B8").Value = Sheet3.Range("G" & projROW).Value 'billing address 4
        Range("B9").Value = Sheet3.Range("H" & projROW).Value 'billing address 5
        Range("E5").Value = Sheet3.Range("I" & projROW).Value 'shipping address 1

        If MsgBox("   This client does not exist. Would you like to add them?", vbYesNo) = vbYes Then
            Sheet4.Range("M1").Value = "NEW"
            AddClientForm.proNAME.Value = Range("C13").Value 'new project name
            AddClientForm.Show
