Dear Sir/Madam,
One of the marketing company request us to add a custom iFrame on the checkout page with basic information.
The iframe should contain the order number and its amount.
Do any one can help to instruct me which file I shall modify to add this iframe including the order number and amount?
P.S. Our cs-cart has several storefront, how can I do this for specific storefront?
Best regards,
Kelvin.
