populating fields from db through list/menu

[kaddu747]

Im creating a commodities calculator.The commodity name,Exchange name,contract size and other details are stored in a database.When the user selects the commodity displayed in a drop down box I need the respective fields (contract size,Exchange name etc) to be populated with data from the database.I already wrote the JS to do the calculation but am stuck here.

Any help would be really appreciated.

You have to send displayed commodity to the datbase and then read the corresponding contract size and other you..after you can make your calculation and display the result..

you should also give your code so we can help you better
