[thelist] form/image button problems

[CDitty]

Hello all.  Can someone please tell me why this form image button refuses 
to be detected?

<input type="Image" name="button" src="graphic2.gif" border="0">

I know this is soooo simple, but I can't figure it out.   When I click on 
the button, it submits, but it is not detected on the next page.  Using a 
"get" method, this is all that is shown on the 
url.......?button.x=20&button.y=11
This just tells be the coordinates on the button, but not which button or 
it's value.

Anyone?

Thanks

Chris
