Thanks people:thumbsup:, not able to test any of suggestions as my computer is down :sigh: , but when I get a chance, I will let you know how I get on. Thanks again for the help.

Hi, :-\ The scenerio: I would like the user to enter data into a text box, before clicking continue. If the data is numeric then the program should assign it to a variable and continue as it should, but if the data is not numeric, the program should respond with a message alerting the user of this mistake. The question: Is there anyone who can either help me directly or atleast point me in the right direction to work it out myself? Any assistance in this matter would be greatly appreciated.
