I would like to hire a Javascript Developer

We are a small professional football club who are sending reports to some young players through a google form. We have a script and associated files previously developed, but are having problems with a line of code, and would really appreciate some understanding of where we're going wrong and some assistance in sorting it. Here's the code: function sendEmail(row) { var docTemplate = "1dtjuvjAatZyLyejjU4J113p_eC38eD8yrr4vCjTxNxY"; var docName = "RegionalDevelopmentCentreEndOfSeasonReport"; var FIRST_NAME = 1; var PLAYER_EMAIL = 3; var COACH_FULL_NAME = 4; var INDEX = 0; var KEY = 1; // This list matches a particular placeholder in the Google Doc with // the column that placeholder's value appears in in the spreadsheet, // where Col A = 0, Col B = 1, etc.. var formKeys = [[1,"keyPlayerFirstName"], [2,"keyPlayerSurname"], [4,"keyCoachFullName"], [6,"keyDestroyer1"], [7,"keyDestroyer2"], [8,"keyDestroyer3"], [9,"keyCreator1"], [10,"keyCreator2"], [11,"keyCreator3"], [12,"keyGoal1"], [13,"keyGoal2"] [14,"keyGoal3"], [15,"keyPsychology"], [5,"keyDevCentre"]]; var splitFields = ["keyDestroyer1", "keyCreator1", "keyGoal1"]; var source = [login to view URL](docTemplate); var newFile = [login to view URL]("Mid-Season Review"); var copyId = [login to view URL](); var copyDoc = [login to view URL](copyId); var copyBody = [login to view URL](); for(var i=0; i<[login to view URL]; i++) { isSplitField = false; for(var j=0; j<[login to view URL]; j++) { if(formKeys[i][KEY] == splitFields[j]) { isSplitField = true; key = formKeys[i][KEY]; values = row[formKeys[i][INDEX]].split(', '); [login to view URL]([login to view URL]("A"), values[0]); [login to view URL]([login to view URL]("B"), values[1]); break; } } if(!isSplitField) { [login to view URL](formKeys[i][KEY], row[formKeys[i][INDEX]]); } } [login to view URL](); var pdf = [login to view URL](copyId).getAs("application/pdf"); var subject = "RDC End Of Season Report 2016/17"; var body = "Dear " + row[FIRST_NAME] + ",_LB_"; body += "_LB_Congratulations on being offered a place within the Regional Development Centre Programme for next season.
