How to get Dynamically

Hi everyone ,

In my form there are three field naming ; Circle , Location & Description .

Circle contains the lists of states and when any of the circle selects accordingly Location will pop up in the location field .

for eg; if selects Karnataka as circle , in loction field all the Name populated like Mangalore , Bangalore , Mysore etc will be populated .

what i have to do is as i have a large amount of data regarding Description for the various locations .

suppose i selects Karnataka in that case all the details of karnataka will be displayed in the Description field . and so on for the other locations also…, i dnt have the authorization to make changes in the main database what will i do in that situation

is there any way to get the data in description field dynamically coz what i am doing right now is entering all the details manually and this very hectic n laborious task .
