The only way of doing this is with DHTML. With HTML, once the page is loaded, it becomes difficult to change the appearance of the page, like adding more rows to a table or adding more form fields or moving an image from this side of the screen to this side of the screen. The only way to do this type of stuff is with layers and dhtml. I would either recommend finding another solution like saying having your add button go back to the server and reload the page with another row, or start doing some heavy research at www.dhtml.com for some code that will let you do what you want. It would take me at least a day or two to get some code that does that and have it working on both Netscape and IE and in Windows and Macs. Good luck though Bill
