Reply To: Troubleshooting Custom JavaScript Variables in Google Tag Manager

The issue comes from the fact that you’re trying to use regex on the wrong kind of object. The document.body is an HTML object, not a string. If you want to scan the body of your HTML for a specific word, you need to convert the body to a string first. You can use the innerHTML property to achieve this. Your function would then look like this:

`javascript
function() {
var bodyContent = document.body.innerHTML;
var result = /stellar/.test(bodyContent);
return result;
}
`
So with this update, you are checking if the word “stellar” is anywhere within the HTML of your body, not within the body object itself.
