 Set Cookie Javascript Function
You need to put the name and values in quotes when you call the function, like this:
Set_Cookie( 'mycookie', 'visited 9 times', 30, '/', '', '' );. 
Don't forget to put in empty quotes for the unused parameters or you'll get an error when you run the code. 
This makes the cookie named 'mycookie', with the value of 'visited 9 times', and with a life of 30 days, and the cookie is set to your root folder.
The Set_Cookie values for 'domain' and 'secure' are not utilized. Use 'domain' on the Javascript cookie if you are using it on a subdomain, like widgets.yoursite.com, where the cookie is set on the widgets subdomain, but you need it to be accessible over the whole yoursite.com domain.
It's good practice to not assume the path to the site root will be set the way you want it by default, so do this manually as a rule, '/'. If no value is set for expires, it will only last as long as the current session of the visitor, and will be automatically deleted when they close their browser.
