There are many errors in your code.

Reserved words function , var , for , if and return they must go completely in lowercase.
On line 5 of your code, the variable summation must be in lowercase.
Also on line 5, you are adding the variable summation and months when you should add summation and 1.

In the end, your code should look like this: (already correctly embedded)

function cantidadDeMesesConGanancias(meses) {
    var sumatoria = 0;
    for ( var i = 0; i < meses.length; i++ ) {
        if ( meses[i] > 0 ) {
            sumatoria = sumatoria + 1;
        }
    }
    return sumatoria;
}

In whatever programming language you have to try to use the notation camelCase in the definition of variables and functions. On the other hand Javascript as every language has a set of reserved words MDN Javascript reserved words

at the end the code should stay like this:

function cantidadDeMesesConGanancias(meses) {
var sumatoria = 0;
for ( var i = 0; i < meses.length; i++ ) {
    if ( meses[i] > 0 ) {
        sumatoria++;
    }
}
return sumatoria; }

Because you do this:

Sumatoria=sumatoria+meses;

It should be:

sumatoria=sumatoria+1;
