Hi KoolPHP Inc,

Followed the example provided below, but resulted in " syntax error, unexpected '=>' (T_DOUBLE_ARROW), expecting ',' or ')' ". Appreciate your help.

<?php
use \koolreport\processes\Group;
class MyReport extends \koolreport\KoolReport
{
    public function setup()
    {
        ...
        ->pipe(new Group(
            "by"=>"country,state",
            "sum"=>"polulation"
        ))
        ...
    }
}

I added 'array' and it works!

<?php
use \koolreport\processes\Group;
class MyReport extends \koolreport\KoolReport
{
    public function setup()
    {
        ...
        ->pipe(new Group(array(
            "by"=>"country,state",
            "sum"=>"polulation"
        )))
        ...
    }
}
