Hi Cindy,
I'm running into an issue, non related to OPC but that is affecting it. The way ZC works when it comes to free shipping (free options) and gift vouchers is a bit odd. Ideally if I offer free shipping over $100 and the customer applies a $10 discount coupon for example, free shipping should not apply anymore. However the reality is, with the way ZC is designed free shipping still applies because freeoptions works on order subtotal not order total.
The way I've made it work in the past was by hiding the place order button if certain conditions do not apply. I wrote a rudimentary piece code (perfected by @mc12345678 a little while back, to whom I will forever be grateful to) but I can't make it work with OPC.
The code determines if both discount coupons and free shipping are loaded and if the order total drops below the free shipping threshold, then the button is hidden, for the most part. I placed the code in the tpl_checkout_confirmation_default.php on the native ZC checkout which is where the place order button displays. On OPC that could be according to what I've noticed the module works, on the tpl_modules_opc_submit_block.php, but it just doesn't work, and I was wondering if you could take a look and maybe point me in the right direction?
This below is what I have.

When loading the page I get a popup "Please contact the store owner; some required elements of this page are missing" and in the logs "PHP Parse error: syntax error, unexpected end of file in /includes/templates/responsive_classic/templates/tpl_modules_opc_submit_block.php on line 68."
Thanks in advance for your guidance.
