it was a stupid mistake... Thanks a lot!!

Just to make it very clear in the beginning, this is my first time trying fxdreema.
So I am trying to make an EA that buys when the end price of a candle stick breaks out of the ±2σ of BB.
And I keep getting these errors. Where have I gone wrong here??

Compilation errors
