If you are in a party of your own, with no other people, the quest will start as soon as you 1) click on the quest scroll in your inventory and then 2) click on the blue "invite party" button at the bottom of the quest's pop-up page. You'll then be able to see the quest on your party page (you might need to reload that page, and wait for it to fully reload, before the quest will appear).

If you are in a party with other people, the quest will not start until all people have accepted or rejected it, or until you click on the "begin" button on the party screen.

Read the wiki page about Quests for more information. If that doesn't help, give us more information about your circumstances. For example, are you in a party with other people? What happened when you clicked on the quest scroll?
