js:

function reloadshowform() {      var fill_pos = $('#fill_position').val();     window.location.replace(window.location.href + "&fill_position=" + fill_pos); }

you have parse parameters @ first.

function geturlparameter(name) {     return decodeuricomponent((new regexp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null; }
