I have 2 problems,
1. usual problem, marker is not in center of the view panel.
2. how can I set latitude and longitude instead of address?

I use this code to show the map:

 try {
    $('#map').gmap3({
            action: 'addMarker',
        address: "No 8, N Khayyam, Urmia, Iran",
            map:{
                center: true,
                zoom: 14
                },
            },
        {action: 'setOptions', args:[{scrollwheel:true}]}
    );
} catch(err) {

}

and the website address is: Proma9 the latest tab menu.
also the latitude and longitude is: 37.546245,45.066581

Thanks for your help
