Share Dropbox Download On Laptop With Mini Ipad

When I downloaded Dropbox on my laptop, the introductory information offered a list of 'tests' to take to win a prize. When I clicked 'test' to share Dropbox with other devices, intending to have simultaneous access on my mini iPad, your program connected me back to download sequence again. Repeated attempts to get multiple hookups gave same result. How to achieve multiple-device access/use of Dropbox, thank you, and do I still qualify for prize, since this would have been the fifth 'test' I passed. Thanks your attention to my question. Sarah
