Form checking ... again!!
My problem:- I have a form that posts to another page when submitted. Now I need to add in a checkbox on the form. If the checkbox is ticked the form can be submitted to the next page, but if it is not ticked I want to have a warning popup with Yes No buttons on it. If they click Yes it will post to the next page, if they click No the form will not post, allowing them to either tick the box or make other changes.
Any ideas, hints, tips would be greatly appreciated.
