Flash + Google AdWords. clickTAG???? Confusion.

[MattSepeta]

Our company is going to up the ante in our adwords campaigns, and I have been asked to create a few Flash banners to test.

Problem: I have not used flash since high-school really.

Question: Do I need to actionscript in the

"on (release) {
getURL("http://www.SITENAME.com/", "_blank");
}

into the banner, or will google handle the hyperlinking when they host the banner?



2nd question: I am trying to wrap my head around clickTAG and am pretty confused. According to googles FAQ, the proper script is

on (release) {
if (clickTAG.substr(0,5) == "http:") {
getURL(clickTAG, "_blank");
}
}

but according to a few 3rd party sites I found, they say to use this script:

on (release) {
if (_root.clickTAG.substr(0,5) == "http:") {
getURL(_root.clickTAG, "_blank");
}
}

Now, do I insert that script into a new transparent button layer, or can I tack it onto the hyperlink button layer (If I even need that)?

Long story short: I am super-confused. Can anyone help my get this cleared up??? Thanks!
