Hi Zaliyanna,
Thanks for your answer.
Yes :-)! Welcome to the "Restriction Plugin" concept.
Restriction plugin are used for that, to restrict the display of value (content view) in relation with some rules.
Example, the language restriction plugin is used to display a value of a field only if the current user language match a define language
Your need is very closed from the Field Restriction Plugin http://www.seblod.com/products/19160 . But it's not enough, it's not working for date and don't manage a comparaison between 2 fields.
The solution should be to create your own Restriction Plugin.
See full list of restriction plugins here http://www.seblod.com/products?seb_item_category=112
Thanks.
