add row to listbox and sum the values of the rows

[xicana]

I have a dropdown (Access 2003) that reads from an inventory table. I want to be able to select an item, click on a button to add the description and the price of the item to a listbox. I want to be able to add the prices of each item in my listbox (think of a simple point of sale system) and have a running total displayed. I'm assuming I must have two listboxes, one will display the description and the other will display the price. I should also have a text box that calculates a running total. I remember doing this in VB a few years ago (in school actually) but I don't remember the syntax.
