Falling Snow for Flash CS4/AS3 -- Need to add click tag

1

I just used the script from the "Falling Snow for Flash CS4/AS3 " tut. I need to add click tag to this for a banner and make it stop after 30 seconds. I am currently trying to use the click tag I always use (see below), but it seems to overwrite the snow script and the snow will not fall.

clicktag_but.onRelease = function() {
getURL(clickTAG, “_blank”);
};

Any ideas? Thanks!
