问了几次了，多段线的长度怎么获得

问了几次了，多段线的长度怎么获得
劳烦版主回答了几次，
但我运行时却报错呀

贴出我的源程序
Sub Count_len()
    ' 创建新的选择集
    Dim sset As AcadSelectionSet

For i = 0 To ThisDrawing.SelectionSets.Count - 1
ThisDrawing.SelectionSets.Item(i).Clear
ThisDrawing.SelectionSets.Item(i).Delete
Next
On Error Resume Next
    Set sset = ThisDrawing.SelectionSets.Add("SS0")
   sset.SelectOnScreen
   Dim entry As AcadEntity
    Dim l_text As String
    Dim l_l As Double
    Dim Arc_count As Integer
    Dim Line_count As Integer
    For Each entry In sset
      '如果是多段线或曲线的长度，就不行了
      If entry.ObjectName = "AcDbArc" Then
      l_text = l_text & "+" & entry.ArcLength
      l_l = l_l + entry.ArcLength
      Arc_count = Arc_count + 1
      ElseIf entry.ObjectName = "AcDbLine" Then
      l_text = l_text & "+" & entry.Length
      l_l = l_l + entry.Length
      Line_count = Line_count + 1
      End If
    Next entry

ThisDrawing.Utility.Prompt vbCrLf & Arc_count & "个弧," & Line_count & "条直线. 共" & Arc_count + Line_count & "个对象." & vbCrLf & l_text & "=" & l_l & vbCrLf
End Sub
