[Javascript] Re:posting arrays

[Bill Marriott]

Thanks for that Esther,

I think your code should work.
However I have decided not to use this approach now.
I think I'll end up with too much code on the page ( the page has 4 of these
tables that I need to cater for) and the display time will be too slow for
the remote users. But I'll store your idea for later.
