// Step 1:
// Between the quotes, type what the alert box message shall say when

// To force a line break, use "\n" (without the quotes).
// For no message, type "" (nothing between the quotes).

// Between the quotes, type what the alert box message shall say when
// the credit card is known and the number did not pass?
// To force a line break, use "\n" (without the quotes).
// For no message, type "" (nothing between the quotes).

Step2Message = "Credit card number is invalid.";

//
// Step 3:
// Between the quotes, type what the alert box message shall say when
// the credit card is unknown and the number passed?
// To force a line break, use "\n" (without the quotes).
// For no message, type "" (nothing between the quotes).

Step3Message = "Credit card is not known.";

//
// Step 4:
// When the credit card is known and the number passed,
// the script can display the credit card type and the
// number (stripped of hyphens and other non-digit characters).
// To display this message, type a Y or a y between the quotes.
// To not display this message, type "" (no space between the quotes).

// ccType          - The name of the credit card, if determinable.
