# Track UTMs in HubSpot Form Module (Page Builder)

Add the form module into your page. 

After that insert our UTMSimple script as explained here: [Where is the tracking code?](https://docs.utmsimple.com/books/101-lets-start/page/where-is-the-tracking-code)

And add the following snippets anywhere in your page:
```
<script>
window.addEventListener('message', event => {
   if(event.data.type === 'hsFormCallback' && event.data.eventName === 'onFormReady') {
      	setTimeout(() => {
            let form_id = event.data.id;
            let f = handlj("[data-form-id='"+form_id+"']");
            f.serializeArray().map(x=>{
                let cookie_val = Cookies.get(x.name);
                if (cookie_val && cookie_val != ''){
                    f.find('input[name="'+x.name+'"]').val(cookie_val).change();
                }	
            });
        }, 1000);
   }
});
</script>
```
