Close not visible Excel workbook in ACCESS2010

I have a process that if it is interrupted can leave the workbook open but not visible  So, if the user runs he process again, I get a a read only message, but there is nothing they can see to close.  I got the below from another question on EE, but how do I change it to only close the one specific Excel.  That is, I want to have the workbook's name in this procedure.  Also, I commented out the WScript.Sleep 2000 as (1) I don't know what it does and (2) the process did close workbooks without it.  But I want it to only close the one and then exit the procedure.  The name of the workbook to close is "UploadTemplate".
