Hi Chris,
Thanks a lot for getting back to me.
Acutally the sample one got from the noChex official demo site(Merchant).
My customers already have an account in my store, It seems they have to create an account in noChex to complete the payment process.
In the demo, there are few payment processor icons available on the page as well as user can select one of the payment processor to complete the payment process.
It would be grateful if you could help me out.
P.S. I've attached the file for your reference.
