Hi guys, I have tried to look both on google and on the site, but have found nothing.

My first questions is that I am using a chainedmenu ("goto" option), everything is perfect but the only thing is that I need a confirmation page, Where on this page there will be displayed the options that the user selected.
Is this possible to achieve?

Secondly, I have a text box on my site where the user inputs a number from 50 to 500, I would need to have the number inputed checked to see that it is of the correct formatm scale. How can I do this?

Any help I recieve will be very very appreciated
