How do I format multiple lines in the cMsg: field in email

Hello,

I'd like to have a multiple line message in the body of the email. I can get the text to be included, but all in one line. How do I get the lines to be separated into several separate lines? Everything except the formatting of the message works fine. Here is my script, that isn't working:

     app.mailMsg({

          bUI: false,

          cTo: "",

          cCc: "includedaccounting@fheg.follett.com;",

          cSubject: "True up Complete" + " " + page1.storeInfo.arMajor.rawValue + " " + pages1_3.page1.storeInfo.storeNum.rawValue,

          cMsg: "Hello,"  ;       

          + "The true up for this store has been completed. Please find the links to the checklist and reconciliation below.\n";

          + "Checklist: \n";

          + "Reconciliation: \n";

          + "Thank you, \n";

    }}}}});

Thanks,
