however did not want the players to come into the group there is a possibility of putting to not send group in an area or specific area?
What?
I'm not sure if there's a way in Lua with which you can prevent group invites from actually being sent.
However, you could do it by removing the player from the group if he gets invited,
while being in an area where grouping up is not allowed. You'd also need to remove players from
a group, whenever they enter a prohibited area.
This script should do all that: http://paste2.org/GHcwCMG5.
Area id's can be added to the table at the top.
