Background video wont play

Hi Im having problem playing a Background video on my site. The video is in the Donation section. Its a video of fireworks it only plays when you click on the donation section twice. It does not play when your in another section of the site and you click the donation section once. Iv left a link to the site below. Please help this site is for a charitable cause.
