payment module

[elainefleur7]

Hi

I have created a website, and installed osCommerce. My host (justhost) tells me that all is fine, but when I try to act like a customer just to test it I get stuck at the checkout

It tells me to review login details, and sometimes says there are payment module errors

Could somebody be kind enough to explain in simple terms

 

How i check my shop is live

and

If the payment should work automatically, or if I have to contact Paypal

 

I have installed the paypal modules

Thanks

Elaine
