checkbox - Jquery, Show/hide div, label for issue

I'm wondering if anyone can help.

I'm having a little difficulty with showing/hiding a div based on a click on a checkbox and its label.

If I have label for along with the id of the checkbox, it calls the jquery twice, which shows and then hides the div I wish to either be shown or hidden (depending on what the current state is)

The JS/Jquery is here:

The problem with the above is that it shows and then hides the div in question. Or hides and then shows. Depending on which is currently available.

The problem with the above is that although the text is clickable and works with the jquery function. I cannot get the checkbox to be checked or unchecked if you click the text.
