Thanks Chad for your reply, i really appreciate it!
With reference to: "Well, I think what you are trying to achieve here is a game that analyzes the user inputs if they have a typo and the input is close to the required text then it will accept it." Yes! this is exactly what i am aiming at. You are on the same wavelength with me on this.
By the way, i have anticipated someone suggesting using so called "regular expressions" and i am moderately happy there is something neater than getting my head around the "elusive" regex.
I am looking forward to your next relpy!
