credit card not valid in checkout

I needed to rebuild my check out pages and now its saying the paypal sandbox cards noare not valid..... I was testing with them before and they were fine. Any ideas why its not accepting any credit cards?

Also to make sure I'm getting the right error messages, I use web payments pro US, but the UK one is the only selection for that. Right now I'm using PayPal Direct, is that the correct one?

Thanks,
Tim

When you are testing with the sandbox you will need to login the the developer center and create your test users. You can have cc info for the users that you can use to test transactions on your site. You must ensure though that you are going to the Sandbox instead of the live PayPal site. In your checkout server behavior there is a use sandbox option, make sure this is set to true.

When it comes to the error messages I'm not sure about what you are asking here. You should be able to expand the bindings for you checkout on the page and drag and drop the bindings for the error message directly onto the page. The bindings you have for this should be based on the local checkout you are using. You can add the bindings by going to add > eCart > checkout > local checkout response, then choose the direct pay option for the Payments Pro.
