How to set class="active" in jquery

I have a sample code:

<div class="box">
        <div id="banks">
            <ul>
                <li class="active1">Bank1</li>
                <li">Bank2</li>
            </ul>
        </div>
        <div id="buttons">
            <ul>
                <li class="active2">USD</li>
                <li>EURO</li>
            </ul>        
        </div>
</div>

And jquery:

<script>
$(document).ready(function(){
    $('.box li').click(function(){
        $('#banks li').removeClass('active1');
        $('#buttons li').removeClass('active2');
        $(this).addClass('active1');
        $(this).addClass('active2');
    });    
});
</script>

OUPUT: Error when click on:

<div class="box">
        <div id="banks">
            <ul>
                <li class="active2 active1">Bank1</li>
                <li class="active2">Bank2</li>
            </ul>
        </div>
        <div id="buttons">
            <ul>
                <li class="">USD</li>
                <li class="">EURO</li>

when removing the class you are looking only inside the #box change it to .box like

$('.box li').click(function(){
    $('.box li').removeClass('active1');
    $('.box li').removeClass('active2');
    $(this).addClass('active1');
    $(this).addClass('active2');
});

AS I understand you need to be able to choise single option in each section. Use only one active class and change styles in css:

html:

<div class="box">
        <div id="banks">
            <ul>
                <li class="active">Bank1</li>
                <li>Bank2</li>
            </ul>
        </div>
        <div id="buttons">
            <ul>
                <li class="active">USD</li>
                <li>EURO</li>
            </ul>        
        </div>
</div>

js:

$(document).ready(function(){
    $('.box li').click(function() {
        $(this).siblings('li').removeClass('active');
        $(this).addClass('active');
    });
});

css:

.box li { cursor:pointer; }
#banks .active { color:red; }
#buttons .active { color:blue; }
