Condition to skip data is not working as intended - email

Question

Hi everyone I copied this from a previous post and matched it up to my needs. I'm having trouble preventing it from sending the entire list when the word Sent is in column 10. I've messed with the coding more than I would like to at this point and feel it's getting messy.
Can someone take a look at it and see what is missing?
It will send the email and do everything I need, but so far it just sends all the lines of data regardless if Sent is in the column or not.
function sendEmails2() {
//setup function
var ActiveSheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var StartRow = 2;
var RowRange = ActiveSheet.getLastRow() - StartRow + 1;
var WholeRange = ActiveSheet.getRange(StartRow,1,RowRange,11);
var AllValues = WholeRange.getValues();
var message = "";
//iterate loop
for (i in AllValues) {
//set current row
var CurrentRow = AllValues[i];
//define column to check if sent
var EmailSent = CurrentRow[10];
//if row has been sent, then continue to next iteration
if (EmailSent == "sent")
continue;
//set HTML template for information
message +=
"<p><b>Sales Rep: </b>" + CurrentRow[0] + "</p>" +
"<p><b>Case ID: </b>" + CurrentRow[1] + "</p>" +
"<p><b>Name: </b>" + CurrentRow[2] + "</p>" +
"<p><b>Signing Date: </b>" + CurrentRow[3] + "</p>" +
"<p><b>Draft Date: </b>" + CurrentRow[4] + "</p>" +
"<p><b>Sign to Draft: </b>" + CurrentRow[5] + "</p>" +
"<p><b>Enrolled Debt: </b>" + CurrentRow[6] + "</p><br><br>";
//set the row to look at
var setRow = parseInt(i) + StartRow;
//mark row as "sent"
ActiveSheet.getRange(setRow, 10).setValue("sent");
}
//define who to send email to
var SendTo = "my email address" + "," + "";
//set subject line
var Subject = "NEW DEAL CLOSED";
//send the actual email
MailApp.sendEmail({
to: SendTo,
cc: "",
subject: Subject,
htmlBody: message,
});
}

Answer 1

mistake is there in var EmailSent = CurrentRow[10] where the column being considered actually in 11. When taking the whole data range from sheet, the column index starts from 0 and so the actual index to be taken should be 9 for 10th column
//define column to check if sent
var EmailSent = CurrentRow[9];
