Newbie Question Re Google Event Script Values

[MarkXS]

Hey, guys sorry for the newbie question. Just moved over to Shopify from BC and can't work this out.

We need to add values to this script. Can you help, please?

We are a UK Shopify User.

<script>
gtag('event', 'page_view', {
'send_to': 'AW-1067871113',
'value': 'replace with value',
'items': [{
'id': 'replace with value',
'google_business_vertical': 'retail'
}]
});
</script>

Thank you in advance.

Mark
