Combo Box loading undesirable values

Question

I’m with two Selects on the page that are interdependent.

In the first SELECT I select the Flag and on according to all the stores that belong to that flag. And I have a third field where I wish to store the ID of the selected store. Only when I visualize in the browser, come the two Combo Boxes (SELECT), but the field INPUT TEXT won’t come.

When I select the first Combo Box, the returned URL is ?fnc=gfi&ans=14&bandorc=47 and is automatically appearing set to company 11 on INPUT TEXT.

When I select the second Combo Box, the returned URL is ?fnc=gfi&ans=14&emp=4 and the INPUT TEXT.

If I run the query in Phpmyadmin the result is this:

My code is like this:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
    $('input[type=radio]').change(function() {
        $('input[type=radio]:checked').not(this).prop('checked', false);
    });
});
</script>
