this is my code for checking whether the start date is before the end date. Even when i run the code and when i try to save it, it displays a message "object does not support this property or method". it aslo says "cant execute freed script. I am sure that the above code is perfect. But i am not able to execute. Can anyone help me?

This may be besides the point - but why the heck would you use a textarea for a date field? Wouldn't a simple text field be better / simpler?

As for the rest of it - you might try commenting out most of the code and slowly un-commenting it until you figure out what's causing things to break.
