The code below get no errors but, does not pull data from the database. At first, I thought it just wasn't loading into the table. I tested it by adding echo statements to see if the query pulled any data. Nothing was displayed. I can't finish the chapter if I can't get this.

loss or broke even */
function calculate_differences($takings, $cost) {
$difference = $takings - $cost;
if ($difference < 0) {
$difference = substr($difference, 1);
$font_color = 'red';
$profit_or_loss = "$" . $difference . "m";
} elseif ($difference > 0) {
$font_color ='green';
$profit_or_loss = "$" . $difference . "m";
} else {
$font_color = 'blue';
$profit_or_loss = "Broke even";
}
return "<font color=\"$font_color\">" . $profit_or_loss . "</font>";
