Hi Bala,

Using a callback in an onSubmit function does not really make much sense.   You definitely want to use a callback with onChange scripts because you do not want to lock the screen on the user while they are adding information.   When they click on the submit button, the user is done, or at least they think they are, until you evaluate the dates.    

I would stick with the getXMLwait().

Thank you so much Vinoth.

Hi,

You should be adding return false in the main onSubmit function.

function onSubmit() {

return false;

}

It wont work if you add a return false in your callback or any sub functions. You should be returning back a false flag to the main onSubmit function and then call return false from it.

Thanks
