Hello,
I am very new to using dBox, but almost have a mapping site that is ready to
go. The only problem I have at this point is that I can not get teh zoom out
tool to work. The code is pretty musch the same as the simple example Steve
Lime gave me execpt I am trying to use a pulldown list instead of radio buttons.
My site is at:
http://216.203.113.94/JasperMaps/LandCorner/LandCorner.html
Does anyone have any ideas what I am doing wrong?
Thanks much!!

It looks like it partially works; clicking around recenters the map,
but doesn't change the scale. The two parameters that MapServer is
evaluating for a zoom-out are zoomdir and zoomsize. zoomdir needs to
be -1, 0 , 1 for zoom-out, pan, zoom-in, respectively. zoomsize is
scale factor, typically 2. Soo look at those two parameters. I'm
betting that one is being set incorrectly.
I use a chuck of code to display client side info which I am pasting
below. I use it to quickly see what is being passed to MapServer. You
declare a var "showDebugInfo" and to turn it on or off, and you add a
<div> "debug"</div> at the bottom of your page to display the info.
