event not defined in firefox

[fei2shop]

Hi,

I have put the fabrik checkbox example js code into a checkbox element:

var v = event.target.get('value');
if (v === '4' && event.target.checked) {
    this.subElements.each(function (a) {
        if(a.value !== '4') {
            a.checked = false;
        }
    });
}

It is work in IE or Chrome, but not in Firefox, and the error I get is "event is not defined". Can anyone give me some guidelines on how to make it work? Thanks.

Which example code? And what do you mean by "into a checkbox element"?

Things change over time, so old examples don't always work.
