In order to track your AdClicks on your flash banners, you will need to create them in a slightly different format.

Here's the steps for Swishmax:

Click Script tab.
Click "Add Script -> Events -> Button -> on(release)"
Click "Add Script -> Browser/Network -> getURL()"
In the "URL:" field enter '_root.click' (minus the quotes)
Click on "(e)" next to the "URL:" field to turn off the quotes around _root.click.

The script should look like:

>on (release) {
   getURL(_root.click);
}

Export the file as a .swf

Macromedia Flash Instruction

To allow the tracking of clicks please create the following action in your banner's button:

on (release) {
   getURL(_root.click);
}
