error: use of unresolved identifier 'router' in main.swift

Hi, I created a bot based on the "hello-bot". And when I was trying to compile, I got these errors: error: use of unresolved identifier 'router' and error: use of unresolved identifier 'router' (but on the line 26). So, what do I need to do to solve the problem?

• the 26th line isn't a problem (I just removed it as it was in the guide)

Ok, so I just watched the word reverser bot's code and then I added this string: let router = Router(bot: bot)
