Square Payment Module for Zen Cart [Support Thread]

[dkerfoot]

ZC 1.5.4
PHP 5.6.40
MySQL 5.7.28
Square 0.97

Hoping for some help troubleshooting SQ-NONCE-FAILURE. Understand it is probably in my template's tpl_checkout_payment_default.php file. I have done some coding in the past, but this is beyond my current understanding of ZC. To me, line 22 below (not numbered, sorry)
<?php echo zen_draw_form('checkout_payment', zen_href_lin
looks to me to fulfill the "<form> element with a name="checkout_payment" in it" requirement, but there is much I don't understand. :)

Console errors:
Uncaught ReferenceError: $ is not defined at index.php?main_page=checkout_payment:100Uncaught ReferenceError: $ is not defined at index.php?main_page=checkout_payment:188

Using a Template named Cold_Steel

Please?
