[Don Calito]

Hello

I just compile an EA i am getting one error : '1' - expression not boolean

When i go to line this is the code causing the error :  if(IsStopped())return(-1);

How do i fix this?

I appreciate the help

When i go to line this is the code causing the error :  if(IsStopped())return(-1);

Boolean is true or false.

-1 isn't a valid return value if a boolean is expected.

Anthony Garot:

Boolean is true or false.

-1 isn't a valid return value if a boolean is expected.

Thank you for your reply, so i should replace it the code with this? if(IsStopped())return(false);

Yes, but it depends on the declaration of the procedure that you created.

The return value must be the data type when you declare the function.

Eg:

int yourFunction(){

     If(something){

          return 1;//Or any integer number.

     }

}

bool yourFunction(){

     If(something){

          return true;//Or false.

     }

}

I did not create the source code, i merely just compiled it and found this error. The question is do i put true or false ?

How can we answer with confidence if you do not display the contents of the code or function completely here :)
