Checkout button in opencart

I have a checkout button on my website that skips the process of adding a coupon. Here is an example: Right now it goes here: [login to view URL] I need it to go here: [login to view URL] The solution I found online is a simple change in the code. It has to go from here <a href="<?php echo $checkout; ?>" to <a href="<?php echo $cart; ?>" I need someone to fix this for me and allow the checkout process to include adding coupons, instead of going directly to the checkout process.
