First, put a stop action on frame 160 in the test2 layer, so the movie stops looping.
So you're using Flash 5 and that's why you ain't seeing properties on a right click.
Note: while testing a movie, if the output box comes out, it means you have an error somewhere!
First your get URL should look like this:
getURL ("
"blank"

;
There shouldn't be the <;> after the url... only the <,> before "blank". Posting seems to add the <;>
Don't forget the <">!
You have to specify what you want... open a new window, replace the current one, etc... Have a look in Help->Index->url for further details.
Furthermore this action has to be called by something, so you should add an ON event!
Your action list should be something like this:
on (release) {
getURL ("
"blank"

;
}
There shouldn't be the <;> after the url... only the <,> before "blank". Posting seems to add the <;>
I've just done it and it works!
Good Luck!
;-)
PS: Any good cracks in there?
