Google Sheet to send an email when cell has specific value - google-apps-script

Question

I have a Google Form for students to input data and I would like an email sent to myself or another person if a specific question has a certain answer. In the email I would like the name of the student that submitted the form to be included in the email. The problem I'm having is the email is only sending the information from Line 2 of my Sheet. (I have line 1 Frozen as headers). I need it to pull from the last line of data entered from the Google Form.

Google Sheet Data - https://docs.google.com/spreadsheets/d/1P1RD7My91jLSHS9hgEOBPv5oYnfCJQviN6Nzy_cH7Cc/edit?usp=sharing
Here is my script code:
function CheckStudent(e) {
// Fetch the email address
var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet2").getRange("B2");
var emailAddress = emailRange.getValue();
// Send Alert Email.
{
var studentData = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1").getRange("C2");
var studentData = studentData.getValue();
var message = studentData + ' is not doing well today!' // Second column
var subject = 'Student Daily Check Alert';
MailApp.sendEmail(emailAddress, subject, message);
}
}

If you are already registering the email in the sheet submitted by the form, then is as easy as creating a installable trigger.
You can do that using the event object.
If you are unfamiliar with triggers then I recommend you to have a read at the official documentation in there you can see a few examples of how to create them:
var sheet = SpreadsheetApp.getActive();
ScriptApp.newTrigger("CheckStudent") // You will need to adapt your function
// to recieve the event parameter
.forSpreadsheet(sheet)
.onFormSubmit()
.create();
Once you have executed the previous code then your function will trigger every time someone submit the form.
EDIT
Now taht I think about you can just do the trigger directly in the form object not going through the sheets.
Changing the event object code slighlty:
var form = FormApp.getActiveForm();
ScriptApp.newTrigger('CheckStudent')
.forForm(form)
.onOpen()
.create();
