Sorry about the title not been that explanatory, but I don’t know how to put this shortly.

I’m making a website for a charity song my school made and we have a just giving page where we’ve made about £600 already. What I want to do is have a running total on my site from the just giving page without having to constantly update it several times a day.

Is there anyway I can search that page for the item I want and include it on a page on my site? Like getElementById on javascript or something? I don’t know…
