What error are you getting, @XCCX?

What scope does the JS extension have?

For the rest of the answer I'm goign to assume you're getting a _tcaq is not defined error, and you have scoped your extension to the tag that creates and uses the _tcaq object...

Extensions run before tags, so if your _tcaq object is created by code in a tag then it won't be declared when the extension runs.

It's usually best to declare the variable first, something like:

var _tcaq = _tcaq || [];

that will use the existing object if it exists, and create a new array object if not.

Or you could scope the JS extension to "after tags" which should mean the object has been created by the time the code runs.
