Scraping help

Good morning,
Sorry but I wouldlike to scrape a value from a website. I’m trying to do it with the scrape service included in HA but I’m finding some difficulties.
This is the source URL SOURCE and I would like to scrape the certificate value.

I followed the guide
Fetched the URL on https://try.jsoup.org/ and copied the element
counted the index

There is someone able to help me with this example? thanks

Not sure what the certificate value is exactly but if it is this one below
the in the select you only need: #ctl00_phContents_ctlHeader_lblPrice
