editing and delting rows

[wxdqz]

Cross Browser adding/editing/deleting rows in a table
I have a page which has a button saying add item.
when the user clicks on the button a new window should popup.
In the pop up window there should be a form with all the columns to be added for that row in main wondow. when the user enters the values in the pop up window they should be dynamically added to the main window.
the bottom line is _dynamically adding rows to a table with a form.
i know how to do this is jsp or asp.
but i want it to perform on the client side.

This works well on windows IE and Netscape
but i want it browser independent.
it falis on mac IE and Netscape...
kindly anyone help me . thank you for your time.
