I would think this would be a common issue but I can't find anything on these forums so I assume I'm doing something fundamentally incorrect.

panel.load({url:'seating.htm',params: {event_item_id:1 ,isAdmin:1, user:mike} ,scripts:true});

this works to load the html but the css doesn't load and the parameters(query string vars) don't come through.
I load the parameters in the js using the location var and it just has the params
from the "main" page not the params that were passed in the panel.load above.

also tried this which didn't even load the js file referenced in seating.htm:
url: 'seating.htm?isAdmin=1&event_item_id=1&user=mike',
method: 'GET',
callback: function(options, success, response) {
