"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You use JavaScript
document.addEventListener('load', function() {
  document.getElementById('start').value = dmy();
function dmy()
	var date = new Date();
	return date.getFullYear() + '-' + ('00' + (date.getMonth()+1)).substr(-2) + '-' + ('00' +(date.getDate()+1)).substr(-2);

That does not help me.

You need to tell me how it is not working

1. Is there an error - if so what
2. Is the code not doing what you want it to - if so how did you implement the code - show me the code so I can see what you have done.

General advice when responding on these forums: give enough information for an expert to be able to respond.

If you just say it is not working I cannot possibly know how you have implemented the solution so I cannot help you.

The code I posted I put in this sample and it appears to be working as expected.

You cannot change the default display format of the <input> control currently - you would need to use a custom component for that.
