"State" dropdown menu doesn't work

[Tom1884]

Ps 1.6.1.13, not default theme.
Adding a new address, the "State/Nation" dropdown menu doesn't work and it appears two time in the form. I can open and choose a different country, but it doesn't update the visualization.

Seems to be a javascript error with theme/js/tools/statesManagement.js (attached):

These are the lines including 54 :

function updateNeedIDNumber(suffix)
{
    var idCountry = parseInt($('select#id_country'+(suffix !== undefined ? '_'+suffix : '')).val());

    if ($.inArray(idCountry, countriesNeedIDNumber) >= 0)
        $('.dni'+(suffix !== undefined ? '_'+suffix : '')).slideDown('slow');
    else
        $('.dni'+(suffix !== undefined ? '_'+suffix : '')).slideUp('fast');
}

 

Tried this, didn't work.

Tried to keep only one language, nope.

I suppose the “doubled” menu could be the point.

What can I do?? No ideas!
Tnx you...
