AAM Zones are set within Piano by using a tp.push command, which requires initialization of the tp object (if you haven't already initialized it):
HTML
<script>
// First line here initializes tp object.
tp = window["tp"] || [];
// Zones are typically used to indicate AAM reporting categories
// Here's how you'd create a Zone called "Web"
tp.push(["setZone", "Web"]);
</script>
In order for Piano to recognize your Zones, you'll need to have already added Piano's JavaScript to your pages or do so at the same time as you're adding tags. You can set as many Zones as you like. Zone names are case sensitive.
