[ka-Map-users] viewport width undefined

[Scott Melby]

Brent -

Thanks for the help.  It did turn out to be the '\' that was trailing 
the URL that was causing the JS error that I was seeing.  However, I am 
still having some trouble.  The init.php is returning the following now 
(note corrected scales and server URL). 

/*init*/aszScales=new 
Array(1750000,1000000,700000,350000,200000,100000,50000,35000,20000,10000,5000,3000);var 
map = new _map( 'pams', 'PAMS', 0, 3, 
aszScales);map.setDefaultExtents(-252600,-148033.591,274400,165545.107);map.setBackgroundColor('rgb(255,255,255)');map.addLayer(new 
_layer( '__base__', true, 100, 'gif',false, new 
Array(0,0,0,0,0,0,0,0,0,0,0,0)));map.resolution = 72;this.addMap( map 
);this.tileWidth=300;this.tileHeight=300;this.server = 
'http://dev.keystoneresearchmap.org/kamap/';this.tileURL = 
'tile.php';this.selectMap('pams');

I get no JS errors, but I also get no displayed map.  From a quick look 
at init.php, it looks like the 'new Array(0,0,0,0,0,0,0,0,0,0,0,0)' is 
saying that all of my layers should be invisible at every scale.  But, I 
can't see anything in my map file that should cause this.  All layers 
are set to "STATUS ON". 

Thanks again
Scott
