I am developing a form that is for a product registration. We are going to be giving a special offer to people who bought their product between a set of dates (like Jan1 and July 1 of this year). I'm asking them to enter the date when they bought their product,a nd if that date isn't between those daate reanges, I would like the form to not submit and pop up a alert box explaining that they aren't elegible.
Has anyone ever done anything like this? Any sample you could point me to? Any help greatly appreciated.
Thanks
John
