//menu
function onOpen() {
 var ui = SpreadsheetApp.getUi();
 ui.createMenu('Manual Update')
     .addItem('Import Keywords', 'importKws')//Copy to add additional functions
 .addToUi();
}
var SEARCH_QUERY = "from:noreply@getstat.com subject:Download your STAT report: " //stat report email address and subject
var COMPANY_NAME = "MacMillan Search" //company name variable that we put in parentheses when we create the report in Stat
 
//grab the link from the email
function getEmails_(q) {
   var emails = [];
   var threads = GmailApp.search(q, 0, 1); //get only the latest email - limits!!!!
   for (var i in threads) {
       var msgs = threads[i].getMessages();
       for (var j in msgs) {
         emails.push([msgs[j].getPlainBody().split('Link: ')[1].split('\n')[0].replace(/\s/g, "")]); //extract the link from the email and remove final whitespace
       }
   }
   return emails;
}
//does the heavy lift of taking the email link, unzipping and adding it to the sheet
function updateSpreadsheet(NAMING_ARRAY) {
 var url = getEmails_(SEARCH_QUERY+NAMING_ARRAY[0]+" ("+COMPANY_NAME+")"); //gets the link
 var zipblob = UrlFetchApp.fetch(url).getBlob();
 var unzipblob = Utilities.unzip(zipblob);
 var unzipstr=unzipblob[0].getDataAsString('UTF-16'); //charset this took me way to long to figure out
 var csv = Utilities.parseCsv(unzipstr, "\t");
 var ss = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(NAMING_ARRAY[1]);
 ss.clearContents().clearFormats(); // clear the old contents
 ss.getRange(1, 1, csv.length, csv[0].length).setValues(csv)
 ss.sort(12, false) //sorts by global volume, review which column you want to sort by and adjust accordingly
}
//The settings for each report these 2 variables & the function name are all you need to change
function importKws() {
 var REPORT_NAME = 'Rankings'; //report name minus the company or project name and parentheses
 var SHEET_NAME = 'Rankings'; //sheet name
 var NAMING_ARRAY = [REPORT_NAME,SHEET_NAME]
 updateSpreadsheet(NAMING_ARRAY);
}

that is the issue, the variables that define the subject of the email don't line up based on what you have defined. Based on the Sciprt you posted above your report in STAT should be named exactly:

Briggs GDS (Briggs Marine/Briggs Marine New)

Try recreating the report with that name and see if it works
