Thanks for the reply Going to have a read up on what you said although...
I am not 100% sure this is what i want to do , I have a class which i want to create multiple instances that the user names, this will be unique.
The trouble i am having is that one i have made the instances of the class I need to use methods within the class but to do this i need their name, and how do I do that without hard coding them into the program.
