How do I complete the "99 bottles of beer" puzzle (level 10) [duplicate]

Solution 1:

Based on the screenshot, I think you've found a bug. Solving the "Wheels on the Bus" puzzle is what allows you to get to "99 bottles of beer" puzzle. But based on the red text in your screenshot, you didn't finish solving the "Wheels on the Bus" puzzle.

When I try to recreate the situation you show, I get an error / warning message, and I'm prevented from getting to the "Delete me!" text.

Working on it further, I was able to recreate your situation, by pasting the "wheels on the bus" (without first deleting it again), above the first line and above the last line. I see no way to solve this except restarting the level by typing in :level 10. (And you might consider sending the screenshot to the game author.)
