Flash Banner clickTAG Guidelines

Your Flash banner creative should have a button covering the entire area of the banner that uses the getURL action along with the 'clickTAG' variable and "_blank" as the target window parameter. Here is what the code for the button should look like:

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

Important things to note:

• 'clickTAG' is case-sensitive. Make sure you reference it just as it appears here.
• You must use "_blank" as a parameter for getURL. "_top" "_parent" or "_self" will not work correctly.
• We only support one clickTAG per banner.
• Your creative can not contain any frame anchors
