copy and rename sheet

I have this Var1="0001"
I need to check if in active workbook exists the sheet named "0001" if not exists copy the sheet SERVICE and rename it with the value of var, in this case "0001"

try like

Code:

---

fnd = false
for each sht in thisworkbook.sheets
  if sht.name = var1 then fnd = true: exit for
next
if not fnd then
  sheets("service").copy before:=sheets(1)
  sheets(1).name = var1
end if

---

A slightly faster method.

Code:

---

Sub Sample()
    Dim Var1 As String
    Dim ws As Worksheet
   
    Var1 = "0001"
   
    On Error Resume Next
    Set ws = Sheets(Var1)
    On Error GoTo 0
   
    If ws Is Nothing Then
        Sheets("service").Copy Before:=Sheets(1)
        ActiveSheet.Name = Var1
    End If
End Sub
