Form Validation

hi, i'm mariana
i need to validate the checkbox or a drop out menu in the form.
I have 3 checkboxes and the user will choose just one, but how do I make sure that the form cannot be submitted unless they checked one of the boxes?
please, help
thank you

You can do a simple 'if' statement like:

<script>
function checkIt() {
if (document.forms[0].check1.checked == false && document.forms[0].check2.checked == false && document.forms[0].check3.checked == false) {
alert('no');
}
else { alert('yes') }
}
</script>

Mariana:

I wrote a sample form validation script last week. It demonstrates how the validation works with the FORM tag:

Also, I would suggest using radio buttons instead of checkboxes if you are trying to enforce selection of only one item.
