Adwords conversion problem

Good Morning!
I’ve tried several ways to insert my conversion code on a specific page, but it’s always unsuccessful.
When I put the code right through the “HTML” tab, the Tag assistant displays the “Missing CDATA Comments” error.
Using the “Tracking Code Manager” plugin (https://br.ww.wp.xz.cn/plugins/tracking-code-manager/), “Non-standard implementation” is shown.
In all attempts, in the Adwords Conversions Page, it shows that the tag is active, but has “No recent conversions.”

Google Code:

<!-- Google Code for PaginaOrcamento Conversion Page -->
<script type="text/javascript">
/* <![CDATA[ */
var google_conversion_id = xxxxxxxx;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "XXX-XX-xxxxxx";
var google_remarketing_only = false;
/* ]]> */
</script>
