Subject: Limit checkbox selection using CF & JS
Hi,
Does anybody have any JS or CFscript which will limit selection of
checkboxes from the dynamic created form. I have a form which has some
checkboxes created dynamically depending upn the query results. I want
to
limit selection to 3 only .
Thanks in advance.
