Save an excel file from within a vbscript

Thanks in advance for any help or guidance.   I have a vbscript, pasted below, that opens excel, runs a macro but fails to save and close.

Set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Open(“M:\Test\Test.csv”)

objExcel.Application.Visible = True


objExcel.Application.Run "PERSONAL.XLSB!Macro1"
objExcel.ActiveWorkbook.Close

'objWorkbook.SaveAs(“M:\Test\Test.csv”)
objExcel.Application.Quit
WScript.Quit

I've commented out the objWorkbookSaveAs because it pops up an invalid charater in line 10 - char 20.  Is it because it is located on a network drive?  I can manually save the file.

Thank you
