    Does the above code work? if not what is the problem and/or error message. also if you put it in [CODE] tags in your post it makes it a lot easier for people to read it and spot problems.

    actually you are generating a new random number each time you ask the user for input.

    2. also the random function is also not working properly.
    3. put the code inside while loop

    so might look something like this :
