What is the filename referenced in this script?

The guy that wrote this script is no longer with the company.  When I run it I get a message from Project, "The map with the specified name does not exist.  Verify the name is correct, and try again."  I have checked permissions and disabled antivirus COM addin but cannot get past this message.  Then a users tells me there may have been some excel files deleted.  So I'm looking to recreate the excel files and test the script again.  However, I cannot figure out what the filename should be from the script.  Can someone help me decipher?
