Hi everyone and thanks for taking the time to check this out.

I have a nifty little script that shows/hides content on a single page when an image is clicked, which I have included below.

I am trying to set a cookie that will remember the user's last view (shown/hidden) when they return to the page.

I have never dropped a cookie so I am starting from scratch. I will do some research on this, but of course I need to get this going ASAP so I thought I'd ask the experts in hopes of saving time and learning something.

Thanks so much for your help.

Regards,

Dominick

There are many setCookie/getCookie functions already written. Mine is on the "Samples of my work > Cookies" page at:

James:

Thanks so much for your reply. I've done some reading and understand how to set and retrieve a simple cookie. My problem now lies in figuring out how to:

1) Set a value for the current state (open/closed) upon exit

2) Retrieve that value and restore the state upon return

Thanks,

Dominick

Using the functions on my site:

&nbsp;SetCookie('state', 'condition', '', 30);

&nbsp;condition = GetCookie('state');
