Send email to specific user based on Google Form - google-apps-script

Question

Background: Google Script for Forms creating a phone message log that emails to a specific person as selected.
Need help with the email address portion of the code. I want to have a message sent to an email address based on the radio button with the person's name selected.
function Initialize() {
var triggers = ScriptApp.getScriptTriggers();
for (var i in triggers) {
ScriptApp.deleteTrigger(triggers[i]);
}
ScriptApp.newTrigger("SendGoogleForm")
.forSpreadsheet(SpreadsheetApp.getActiveSpreadsheet())
.onFormSubmit()
.create();
}
function SendGoogleForm(e) {
try {
var email = HELPHELPHELP;
// Optional but change the following variable
// to have a custom subject for Google Form email notifications
var subject = "Google Docs Form Submitted";
var s = SpreadsheetApp.getActiveSheet();
var columns = s.getRange(1, 1, 1, s.getLastColumn()).getValues()[0];
var message = "";
// Only include form fields that are not blank
for (var keys in columns) {
var key = columns[keys];
if (e.namedValues[key] && (e.namedValues[key] != "")) {
message += key + ' :: ' + e.namedValues[key] + "\n\n";
}
}
// This is the MailApp service of Google Apps Script
// that sends the email. You can also use GmailApp for HTML Mail.
MailApp.sendEmail(email, subject, message);
} catch (e) {
Logger.log(e.toString());
}
}

Answer 1

Presumably the intended recipient's name comes from a question / column with a title like "Message for".
In that case, try this:
...
var email = resolveEmail( e.namedValues["Message for"] );
...
function resolveEmail( userName ) {
// List of userNames & (secret) email addresses
var userEmails = {
"Mickey" : "bigears#example.com",
"Donald" : "duckman#example.com" // etc.
};
if (userName in userEmails) {
return userEmails[userName];
}
else {
// Unknown user - send email to script owner
return Session.getEffectiveUser().getEmail();
// Alternatively, could throw an error to get notified
// throw new Error( "Could not resolve email for user: " + userName );
}
}
