Thats because you must wait for the page to load before creating
layers. You should use DynAPI.onLoad = function() {} and put your
code in there. DynAPI.document is not created until the page is
finished loading, thats why you are getting that error. Or you can also
check for DynAPI.loaded in the function makeLayer:
function MakeLayer(){
if(!DynAPI.loaded) return;
layer=new DynLayer(null,Math.random()*400,Math.random()*400,50,50,'#c0c0c0')
DynAPI.document.addChild(layer)
}
