I already know what should be done, but my piece of code does not work

example:

$(function() {
$("#map").goMap({
markers: [{
latitude: 56.948813,
longitude: 24.704004
},{
latitude: 55.548813,
longitude: 23.204004,
draggable: true,
id: 'markerShowHide',
icon: 'img/drag.png',
}],
});

$("#showHide").click(function() {
$.goMap.showHideMarker('markerShowHide');
});
});

and this code must be intagreted in script_list.php at line 79, but i don't know how to connect example code into script_list :\

Greetings to you all,

for user or visitor of your pages, if you have many categories it would be best for user to unchecked or check them to easier way to see primary one. I think this part of coding is pretty important for those who have more than 2 categories with +100 points.

So i was wondering does anyone know code how to show/hide categories points on map?

I made list of my categories(including main three cateogries - 1,3 and 6) with counter in footer, it goes like this

<?php
if (!is_page() && !is_home()){
$catsy = get_the_category();
$myCat = $catsy[0]->cat_ID;
$currentcategory = '&current_category='.$myCat;
}
wp_list_categories('hierarchical=1&use_desc_for_title=0&exclude=12&depth=1& orderby=id&show_count=1&include=1,3,6&title_li='.$currentcategory);
?>

and i think in this part of code, you must put some code to show/hide pin points on map, but i dont know how, i'm not so good in php

I have found this page, example of show hide point by clicking on button (that i want)
http://www.pittss.lv/jquery/gomap/examples.php - (Show / hide marker by click button (v1.1.0) )

with this part on link, it would be pretty simple to do something like this, but i can't it put it togheter.

any help?
