EDIT** I thought I had fixed my error until I found this, what does this mean?

I fixed the first error but that made another error here.

I am pretty sure that's one of the first things the guide i'm following instructed me to do.

Can some one please explain this red line for me. http://imgur.com/NjzSlnn

Thank you dude. Also if someone could explain this simply that would rule http://imgur.com/Y7WzV8h

Yea I noticed that after I posted. Why even take the time to point that out? how does that answer my question?

I might not need help by the time some one replies but I'm trying to learn myself a few things and so far this guide is awesome I understand like 80% I want to know what the different coloured text means. Like the yellow blue and green. Thanks.
