What i need is, if a item in a listbox Doesn't exist, it needs to remove it from the other.
In the pic i have attached. Basically If it doesn't exist in Listbox2 then it needs to be removed from Listbox1 and tell the user which one has been removed.
i.e Test 02 doesn't exist. So messagebox would show "test02 has been removed" then remove it from listbox 1
It probably something simple thats sitting in the back of my mind, but for the life of me can't figure it out lol
