I am making a site for a client and we need to embed their payment resource. The code is as follows
<form name="PrePage" method="post" action="https://Simplecheckout.authorize.net/payment/CatalogPayment.aspx#">
<input type="hidden" name="LinkId" value="d84ba6ff-04bd-4cf3-b979-68eec74dab57" />
<input type="submit" value="Payment" />
</form>
I would like to edit this more button but I would like to know if there was a way with Shopify to override the button taking the user to a new page and instead making it either open in page or in a pop up.
