I've wrote this code on button's dynamic action
apex.navigation.redirect('f?p=102:3:&SESSION.::NO:RP,3:P3_UBR,P3_REQUEST:&P80_UNI.,VIEWBLM');
I want to redirect from page 80 to page 3. and pass the value of &P80_UNI to page 3 using javascript.
When I execute this code it redirect me to login page and then shows error on page 3.
