Question

I am at a loose end as to why my code is not hiding when i untick. I would be grateful if someone could check my code and point out where I am going wrong. I have posted code here. many thanks

You can juse use this.checked

$('input[name=messagetick]').click(function() {
    if (this.checked) {
        $('.contactmessage').show();
    }
    else {
        $('.contactmessage').hide();
    }
});

A slightly better version would use .toggle([showOrHide])

$('input[name="messagetick"]').click(function() {
    $('.contactmessage').toggle(this.checked);
});

Side note, don’t forget your " when using an attribute selector.
