URL variables

I want to load a movieclip into a movieclip the file is retrived from a URL variable

eg.

page.php?url=foo.swf

and have this in my web document:
<PARAM NAME=movie VALUE="index.swf?pg=<?php echo $_REQUEST["url"];?>">

and in Flash

loadMovie(pg)

But I want to have a test where I test if pg is empty or not

eg. something like:

/*
If not pg load default page
/*
if (!pg) {
//Load default page(eg. default.swf)
}
else {
//Load pg)
}

But I just can't get things to work, can anyone help

One easy way to find out if the parameter is loaded into flash or not:

put one dynamic textbox on your stage and name the "var" property of the textbox (not "instance name" of your textbox) to the name of your parameter's name. In your case "pg".

Everytime you load your flash, the text box shall display the pg parameter. If not... soemthing wrong with your HTML code.

If it displays the URL you want:

if (pg.length<1) {
//Load default page(eg. default.swf)
}
else {
//Load pg)
}
