Passing value from parent form to child form using javascript showModalDialog

if I want to pass my value to the confirmation field !!! so let's say that I want to remove item No. 1, so I checked the box and then clicked the delete button. a popup comes out with part number 1 in it.

I implemented a popup using the show modal dialog (JavaScript), but I still cannot get the parent value in the child form!

Also, if I have item number 1 and item number 2, I want both to appear in the confirmation window !!

Any suggestion would be greatly appreciated.
