Great idea but a couple of issues. It's Betio, not Beito. Also, the answer for Doha is not Cameroon. There may be other things to check, but at that point I gave up.
A few errors besides those pointed out by NigelS. You have the Philippines in twice (once with a bad spelling). Also Ecuador. But Dominican Republic is absent altogether. There is probably another absent country but I've not worked out which. Capital of Bhutan is mis-spelled.
This will be a good quiz with a few tweaks.
