这个是怎么回事啊？

How do i pay using mtn mobile money for Uganda! Iam in dire need to pay for this app but the only option i have is for mobile money

I really often have the problem that aide won't download the libraries i added. Any ideas how to fix it?
Regards

I have redone this lesson 5 times. It looks right every time. Yet it has errors, but they don't show up as any red lines. I think it's a glitch. Help. I want to move on.
