Hello, I've been trying to find some javascript on these forums that will work but have had no luck. Thought I would reach out here in the hopes that somebody can help me out. Basically the form is going to be used for Subscription Preferences - 8 checkboxes in total. The last checkbox is 'Unsubscribe from all' - Once checked, I need this checkbox to un-check any other checkboxes that have been checked by the user. Here is the landing page I'm using the test the form: https://page.elmosoftware.com.au/update_subscription-Centre.html If anybody can help point me in the right direction that would be greatly appreciated.
