Nate, sorry it is not quite that easy. You are passing a parameter to an html file. The html file has no way to see that arg and pass it to the Player instance.
This will work if you call the .swf directly, with the querystring parameter. Use Application.application.parameters.test. To do this in a production environment (if the parameters are dynamic) you will need to have a server platform generate the html file. The easiest way to do this is to look at the generated html file that FlexBuilder creates. In the javascript call, you will need to add your parameters to the "flashvars" line in AC_FL_RunContent(... like: "flashvars",'historyUrl=history.htm%3F&lconid=' + lc_id + "&test=system" + '', Of course you will have the server (asp, jsp...) output the actual value you want for "system".
