  2. Are those line numbers actually in your code file?
  3.   }
  95 else   
   97 }
    Else what?
 

Please delete your copy/paste code and attach the file properly instead.

Don't paste it as plain text, especially not with line numbers. It becomes unreadable, especially if it is so long.

Use the "+ Attach file" icon below the text field.

I would have suggested using the "</>" icon, but since you pasted it with line numbers it would not help either. So attach the original ".mq5" file.
