Free Domain Verification and Pointing

Very frusterated here...

Last week I used my open spot for a free domain with my account. The domain was verified with domainpeople and completed on Comcast's end. lpgasequipment.com is the domain.

Problem #1  I tried to point my domain to my website hosting provider (Weebly) and it would not let me publish...DNS settings were incorrect.

Problem #2: I deleted my domain with Comcast and re-added it. Now stuck on verification Step 2. (see photo below) Please fix!

We can wait on problem #'s 3 & 4 until later.

Thanks.
