Need help with sugarcane farm program

Hello, I am new to computercraft. I read so much tutorials that I decided to write my first program. It is sugar cane automatic farm.
I tried it but it didn't work. So here is pastebin link: http://pastebin.com/wNyMiyqv
Hope I can rely on you ;)/> (Sorry if I wrote something wrong: I don't speak English that good :mellow:/>)

What did happen? How was that different to what you wanted?

Uhh it says 'then expected' on line 106, but it is already there…

That means you put something unexpected before the "then". In this case you put "minecraft:reeds", but forgot the quotes around the string.
