        value_template: 0.0

  • Explain what number you are trying to get from that page.
  • Use View Source (not DevTools) to check the number you want is in the original HTML from the server — it might be fetched separately and dynamically inserted, and scrape can’t help with that.
  • If the number is in the HTML, work out a simpler select — you don’t need the whole chain.
  • A common problem is that DevTools builds a tbody into the DOM chain that isn’t in the HTML — check and adjust as necessary.
