Hi All,

I having been getting some help with a custom store that I am building and have been given a piece of code by support that works but I do not understand how and would be grateful if someone could break it down for me.

.(isset($_SESSION['currencySymbol']))?$_SESSION['currencySymbol']:"$".

I understand the isset. So for me this statement says if session "currencySymbol" exists, but I do not know what the ? is for at the end as well as the :"$"
