<script type="text/javascript">
    function toggle(id) {
        var state = document.getElementById(id).style.display;
            if (state == 'block') {
                document.getElementById(id).style.display = 'none';
            } else(state=='none') {
                document.getElementById(id).style.display = 'block';
            }
        }
</script>

else(state=='none') {
document.getElementById(id).style.display = 'block';
}

You don't need to put the expression into 'else' statement. Replace with below:

else {
document.getElementById(id).style.display = 'block';
}

Also, place the codes in code tags.

Tnx!I forgot if!!!:))
