Unable to get property 'reload' of undefined or null reference

syaefa

I use ie to open localhost, but this swf chart can't be access on another pc. and pop up error "Unable to get property 'reload' of undefined or null reference". Thank's a lot

function reload(url)
{
tmp = findSWF("test_chart");

//
// to load from a specific URL:
// you may need to 'escape' (URL escape, i.e. percent escape) your URL if it has & in it
//
x = tmp.reload(url); <---- This
}
