Assistance Required - JavaScript Syntax Error: missing }

There are several syntax errors, I have also added new line for first alert for easier review and condition to second alert to send mail only if answer to alert is "Yes" (let me know if that works for you):

app.alert("Before sending to PC for review, admins please review the following:\n- Travel Application Details\n- Cost Breakdown\n- Private Travel Plan", 3);

var cAlert = app.alert("Are we ready to send to PC for review?", 3, 2);

if (cAlert == 4) {
 this.mailDoc({
  cTo: this.getField("Email Address").valueAsString,
  cCc: "manager@email.com",
  cSubject: "Travel Application " + this.getField("FullName TravellersRow1").valueAsString + " " + this.getField("City 2").valueAsString + " " + this.getField("Departure Date").valueAsString,
  cMsg: "Please see the attached for your review and complete the 'Travel Justification' section. Refer to the form with a yellow box labeled 'Send to Admin', click the box and this will auto-generate an email back to the admin. Admin will then process the rest of your application and progress to the Manager and Assistant Executive Director for review, sign-off, and approval."});}
