Is it possible to get a param input from another param, instead of an input? I was hoping to use multiple params in a query with the same input value.

I figured it out.

If I set it up this way, I'm able to have one input sent to two different params.

protected function defaultParamValues()
{
    return array(
        "startDate"=>"",
        "startDate2"=>"",
        "endDate"=>"",
        "endDate2"=>""
    );
}

protected function bindParamsToInputs()
{
    return array(
        "startDate"=>"startDate",
        "startDate2"=>"startDate",
        "endDate"=>"endDate",
        "endDate2"=>"endDate"
    );
}
