errors in the source code

 

hello guys I have an MT4 indicator, but this is giving me the errors in the source code, as I'm not a programmer I don't understand any of this.

this and the entire code of the indicator, if anyone knows how to solve these error messages, could you help me?

(screenshot of errors is attached)
