I'm a little confused here...

I've finished the cart and I just noticed that if I have 3 items in my cart...

1 x Tea @ $1.50 = $1.50

2 x Book @ 9.99 = $19.98

Total: $41.46

What's with the total being wrong..? I'm a little confused.. Like I said.

@Hug0101 It's not wrong. 2 x 19.98 is 39.96, add 1.50 is 41.46. Unless I'm missing something there.

To those that may geta undefined error just put $sub = ""; and $total=""; before the foreach loop and that will go away.

If you are getting the error: Parse error: syntax error, unexpected ';' in cart.php on line 21

replace the:

$_SESSION['cart_'.(int)$_GET['­remove']]==;

with:

$_SESSION['cart_'.(int)$_GET['­remove']] -='1';

Alexs Id product number is different with yours change this cart_1 To cart_ one of your product  id number !!!!

[BapidBeagle]

Instead of three if statements for Add Remove and Delete try a switch statement to make things more organized.
