2 workbooks but vba routine to keep current workbook open but close saveas copy

I have a vba routine that is not working properly.

I have a current workbook:    I need to keep open
I have a second workbook i'm opening...getting additional string for saveas and then I just need to close the saveas workbook.

Current workbook "MyExcel1.xlsx"

In the code below i'm opening another workbook , doing a SaveAs and Then closing it.
but keeping my current workbook open.

THIS CODE IS CLOSING MY CURRENT WORKBOOK ALSO ?

Public Sub CmeSaveAs()

Dim oldwkbk As String
Dim excelwrk As Excel.Application
Dim newdate As String
Dim sInput As String



Set excelwrk = Excel.Application
  excelwrk.Workbooks.Open "C:\Program Files\Cme\Template_DoNot_Open\Export_Cme_Template.xlsx"
  excelwrk.Visible = False

 sInput = InputBox("Enter File name here")
' saveas and then close please
    excelwrk.ActiveWorkbook.SaveAs "C:\Program Files\Cme\Cme_Export\" & sInput & "_" & newdate
excelwrk.ActiveWorkbook.Close
End Sub

Thanks
