Hi Thanh,

please use myarray without the brackets []:

function arrayCounter (myarray){

BTW a more "streamlined" version would be

function arrayCounter (myarray) {
        if (typeof myarray === 'string' || typeof myarray === 'number' || typeof myarray === 'undefined') {
                    return 0;
        }
                    return myarray.length;
 }

Kind Regards Holger
