BigCommerce Checkout Text Change - Javascript Troubleshooting

I have built a BigCommerce store ([login to view URL]), and have everything done except for one little tiny change within the checkout process. I can't seem to figure out why the Javascript I have been trying is not working at all. To get to the issue, add an item to the cart, and go to the checkout process. When you get to the place to either login or create an account, just select 'Checkout as a Guest'. You can fill out whatever information in the 'Billing Details' as you would like, but make sure that you uncheck the 'I also want to deliver to this address'. The issue lies in the next step. Within the 'Delivery Details', we need the terms 'Customer First Name' and 'Customer Last Name' changed to 'Recipient First Name' and 'Recipient Last Name'. I've tried a number of jQuery and Javascript solutions, including: $("[login to view URL]").each(function() { var text = $(this).text(); text = [login to view URL]("Customer First Name", "Recipient First Name"); $(this).text(text); }); $("span:contains('Customer First Name')").replaceWith( "Recipient First Name" ); But to no avail. I believe the Javascript function that renders the text labels is called after the user clicks the button, so we need some sort of solution that will change this. Can you help? Client is very ansy to get this project completed, so payment will be swift once the issue is fixed.
