How to retrieve values from the last row - forms

Question

I created a Form for requesting new student Google account. I want a Sheets Script to email the person who submits the Form the new account information, which is created via a formula on a "Results" sheet.
function Notification() {
// Send email notice for accounts
var lastRow = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Results").getLastRow();
var range = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Results").getRange("A" + lastRow);
if (range.getValue() !== "") {
return lastRow;
} else {
return range.getNextDataCell(SpreadsheetApp.Direction.UP).getRow();
var AccountName = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Results").getRange("H" + lastRow);
var Password = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Results").getRange("I" + lastRow);
var PW = Password.getValue();
var Account = AccountName.getValue();
// Fetch the email address
var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Results").getRange("G" + lastRow);
var emailAddress = emailRange.getValues();
// Send Alert Email.
var message = 'Account Request - Account Name: ' + Account + ' Password: ' + PW; // Second column
var subject = 'Google Account Request';
MailApp.sendEmail(emailAddress, subject, message);
}
This script is triggered on a new Form Submit. Attempting to pull the values from the last created row queried to a "Results" sheet, using lastRow to find the latest entries row, from select columns. Script runs without error, but no email is sent, telling me that it's not getting the values, or returning null values.
This is the sheet its pulling data from

Answer 1

You are only sending row 2 because you are retrieving only one value (Password.getValue() and AccountName.getValue()). Consider the difference between getValue versus getValues.
On the other hand, by declaring a range such as getRange("H2:H") ("Account Name") you are including every row in the spreadsheet, including rows with and without content.
How would I make it pull the values from the last created row?
There are two options:
getlastRow() (the "Sheet" versus "Range" version) "returns the position of the last row that has content" doc ref here. In fact, that item of documentation has a good example of how to declare a Range using the command.
there is another (very useful) utility described on StackOverflow that is a favourite of mine. This describes the number of contiguous rows, in a column, with content.
I suggest that you declare the range using getRange(row, column, numRows, numColumns).
"row" having been determined using one of the methods described above, "numRows"=1. Then getValues for that range will include only the values in that row, and your email will be sent only in relation to that row.
