Ryan,
What I am seeing is:
Code:
{***
Disable Submit order button once pressed
by:
www.cart-lab.com
for: X-Cart Version 3.5.x
template: customer/main/checkout.tpl
***}
{*** Copy to skin1/customer/main/checkout.tpl ***}
The only instruction I see is too copy it to the template. Is does nto say where in the template or if code gets replaced, etc. Sorry for being blind or stupid on this.
