Cant access to variable value in array : I have array of values

    var info_tab = [
					["Aaaa", 53.12040528310657, 23.258056640625,1,ikona3],
					["Bbbb", 53.09402405506325, 18.0010986328125,2,ikona2],
				];

And here I use it in function to pass value as parameters...
Problem is with this section: label: info_tab[i][1]

    var markers = locations.map(function(location, i) {
          return new google.maps.Marker({
            position: location,
            icon: ikona2,
            label: info_tab[i][1]
          });
        });

And i got error Uncaught TypeError: Cannot read property '1' of undefined.
I i show this via  window.alert(info_tab[i][1]) it shows good value...

Where is my mistake ?
