How can I use the subtotal in an if statement?

[nickc41]

I created a banner for my shopping cart.
The banner displays fine but I only want to show it if they spend over 50 dollars.

I'm just not sure where I can pull that number from

I tried $cartShowTotal and what is displayed in the html header.

Any help would be appreciated

You probably want $_SESSION['cart']->total

so something like

if($_SESSION['cart']->total>50)
{
    // blah blah blah
}
