Well i was already thinking that i am not so clear in my question. so better let me post my model and what i want here .
http://dpaste.com/163776/ sorry I missed by mistake "C" of class Rates while pasting it on dpaste. Anyways there are two models. there is one field billsec in model named "Ast" which is duration of call. there is one field named "dst" which is "dialed Number " . What i want is is to compare this dialed number by the prefix given in Rates Model and then multiply that Rate with duration to show the cost of call. hope i am bit clear now .
