Help Please, Variable Problem (I Think)

I have a SWF as the header to my website.
When the page is loaded, it loads a random SWF from a designated folder.

loadVariablesNum(“billboards/count.php”, 0, “POST”);
loadMovie(“billboards/billboard”+num+".swf", “_root.stage”);

count.php counts the # of swf files in the folder it can choose from and returns a random number for one of them, for example: “&num=3”

it tries to load “billboard.swf” and ignores the num variable, any idea what am I doing wrong?

Thanks!

try eval(“billboards/billboard”+num+".swf")
