Re: [PLUG] how to transact credit cards and PayPal on a web site?

["Mader, Bob" <Bob.Mader@compaq.com>]

I put together a Paypal payment form that uses JavaScript to synthesize the
correct URL based on a user's selections. A good solution if you don't have
access to server side programming (i.e., cgi, php, etc.). The tricky part
was getting the dollar amount formatted right... PayPal will not accept
"2.5" for $2.50... and there's no sprintf in JavaScript...

They currently allow for two URL's, one for success, one for cancel. I
don't know where tried and failed anyway falls.
