Would it be possible to add conversion value to the purchase Facebook pixel?

If you're not already, I recommend using Google Tag Manager. Setup a custom variable to pull the value from the page. Ideally IPB should have a digital dataLayer as recommended by the W3C with this data in there rather than using document.getElementBy* etc to scrape the content.
