I have a rate calculator that when you click the Calculate button, a div displays a message for a few seconds then disappears.
This works great.

However if the Calculate button is clicked again, the div is still hidden.

I need to reset this somehow so each time a calculation is done, it repeats process of displahying the div and then hiding again.

How do I do this?
