I am trying to get an input field to populate with a price when the user clicks a button. the form will ask the user for a product and then given that product when the user click on the price button it should display the price for the product in that box. It is the frameprice function that i want to like the button with the field so that on the click it will display the price in the field. if anyone could help that would be great thanks.
