CVV code in confirmation page

[Guest]

Hello,

 

I am having trouble with the cvv code. Everytime that I confirm the order it says:

Missing CVV2 Data. CVV2 from credit card is required.

 

I don't know where I went wrong.

Then the credit card says invalid when I type in a real number in live mode on the checkout page.

 

Please help me. I need to get this running

 

 

Thank You,

Mike
