You will need to add your own code to do so. </p> https://www.machform.com/forums/topic/credit-card-number-038-validation-038-calendar-question#post-4929 Fri, 06 Mar 2009 17:56:51 +0000 keithdouglas 4929@https://www.machform.com/forums/ <p>Re: Q2.

Tested out the online version and it seems to handle almost everying we need except for the two following scenarios:</p> <p>1. If I use calendar fields and have an arrival date for one and the departure date for another, is there any way to calculate the number of days and place it on the form?</p> <p>2. Is there any way to deal with taking customer's credit card number and expiry date. We do not actually process the card, it is just to guarantee the room. I believe there is also some mathematical formula to verify that the credit card number is legit (as far as the numbering sequence goes).</p> <p>Thank you </p>
