I would say: to me it sounds legal, so I would say, just give it a
try. The worst thing that can happen is that your browser doesn't
like it and displays some error messages.

And please let us know afterwards whether it went well or not, o.k.?

Well could you try looking at www.ednevitible.co.uk/BarApplet.html for
me please, in Firefox it displays a small window, however, it should
show something thats as tall as a single line and as wide as the table,
so in theory as wide as the screen. However, it doesnt seem to do that.

Well I had to replace the code with a parameter so I could show
someone.. I dont think it works using variable widths..
