Hi

I am trying to create an Order Form made up of ComboBoxes, that when selected display a currency value in a textfield. I then want the textfields to add up to a total box at the bottom. New to Actionscript and just trying to get my head around everything.

I’ve done the following so far. Don’t know how to add up the values in the text fields to a total. Any help greatly appreciated
