Hey guys.How do you make so the boxes appear AFTER you select?Also, how do I store the information in the fourth combo box so I can use it in a variable later in PHP?I mean something like "data_2_2_1_2 = new Option("2212","$50")" ?Or maybe a submit box and when you press it the last variable appearsThank you!
