How do I advance from level 335.

I completed 335 and got a message there was an error and I had to refresh.  Of course, I did not get credit for that level.  How do I advance?

Sometimes these thing happen,  bad timing at it's best usually. If you've completed it once, i'd try again. As you have infinitely more chances of passing it again then being put forward by one level honestly. You can do it!
