Login invalid validation message

Hi,

I have added the modal login to one of my menu item.when i click it pops up but if i try an invalid it wont show any try again message or invalid something instead it is just redirecting to the redirection link which i given to it. i was in need to make a login with validation if succeeded than redirect to the redirection link i provided. Hope the plugin was meant to do so…please help if i missed out somthing…thanks
