HTML & CSS Creating an Automatic Email Script in App Scripts, I have done it before, but I am having trouble replacing the info

[SammieBabie1]

I am having trouble with placing the information throughout the script. Can anyone help me?

Here is the link to the sheet as well: https://docs.google.com/spreadsheets/d/1dRIqIhIgFOAgr-e0ex8M_tcLOR9in0Pm8G8gQtChqnk/edit?usp=sharing

[CODE lang="rich" title="Automated Email"]function onSendEmail(e) {

var range = e.range.getA1Notation();

//Check if SendEmail column is edited

if(range.match(/^L[\d]+$/)){

if(e.value == true){

var sh = e.range.getSheet();

var data = sh.getDataRange().getValues();

var rowIndex = e.range.getRow()-1;

//This will prevent sending email if the header is edited

if(rowIndex > 0){

var product = data[rowIndex][3];

var email = data[rowindex][9];

var subject = 'Product Notification';

var body = 'A product you were interested in:' + product + ' is back in stock. Please contact us at 1-800-748-7001 to place an order.';

//Send email

MailApp.sendEmail(email, subject, body);

}

}

}

}[/CODE]
