I recently started playing Candy Crush Saga. I have a problem continuing the game.

I have Level 20 and can not open Level 21 or anything beyond.  All I get is a big pink padlock.  What do I need to do to continue?  Thanks in advance for your help.

This is a roadblock, you will see them at the end of each episode. If you click on the roadblock you will see the options. You can either pay gold bars or if you click the ask friends option it will send out requests and when 3 friends accept them you will be able to proceed.
