On the website I have a form where people have to give in a date.
this date must be at least 7 days ahead from the date of today.
So if they put in a date that is closer then 7 day's to the day of today they must get a error and the field have to be empty again.
How can I dot the calculation for this to happen?

Is there a formula to become this?

Thanks in advance...

have you seen this? http://www.wysiwygwebbuilder.com/forum/ ... 53&t=71849
this is supported in that extension
may be available other solutions for free but i'm not sure if they support the functionality you are asking for
