Some DataGrid questions (export, delete row)

Afternoon Kirupa community,:afro: I’ve been working on a shopping cart and have some quick questions regarding the DataGrid component. I have checked all archives and dont see an answer to my question so here they go…

First off my DataGrid is populated within the flash document, at which point I would like to export both columns to a php which sends it off to Verisign’s payment processor. [COLOR=darkred]How can I assign column data a specific variable?[/COLOR]

[SIZE=2][COLOR=black]My second question would be removing items from the DataGrid. If a user wants to remove a product from their cart, [COLOR=darkred]how would I go about adding the functionality of removing a row from the DataGrid?[/COLOR][/COLOR][/SIZE]

Thanks very much for your responces!
