I have an order form I am creating in Ultradev. The default form shows room for entering only one line item (one row of textboxes for entering data). I would like to create an "add new line item" button and row of textboxes to the form if the user has more than one item they want to order.. I would like this to expand as necessary.

One textbox has an autonumber (item#)
One has an equation that takes unit cost * quantity to generate the total

When I try to create a new line, the autonumber and total cost doesn't generate but the new row does. How can I get it to populate additional rows with the autoinformation?

Thanks
