look mate, learn to use grammer and make your questions eligible, or i'm just going to stop answering them, it took me 3 minutes to get the jist of that =/
you only need one of eitehr of thsoe entities.
there is an example map in the example maps vualt, named aim map example or some sh*t.
you need two func_buyzones, put them in a high corner of your map, totally unreachable, now open one's properties (hihglight it, then press Alt+Enter) and set the Team to Counter Terrorist, open the other buyzones properties and select terrorist only.
now no-one can buy,
I would advise not using both buyzones and an info_map_parameters, as this will cause errors, when you think about it; you have two entities trying to do opposite jobs with teh same function, ie buying.
don't use the map_parameters anyway, it sucks and doens't work all teh time.
