<?php
$result = mysqli_query($DB, "SELECT * FROM salestemp WHERE id = '".$_REQUEST['sid'].
"' ") or die("Error: ".mysqli_error($DB));
$counter = 0;
while($row = mysqli_fetch_array($result))
{
$counter++;
?>

When submitting the form I am met with the "Error Detected: Your Cart Is Empty".
Can anyone help me at all please. Thank you very much in advance.

Answer 1

You have 'ammount' instead of 'amount'.
