random number generator vbscript

Can anyone help me with making a VBScript with the following requirements?

• The user needs to choose a number.
• Generate a random number between 1-100.
• If the user guess the right number it should say "Congrats".
• If the user guess the wrong number it should say if the random number is higher or lower.
• The random number must be generated by the "random" command.
• The program needs to check for errors so the program doesn't crash when a wrong number is put in by the user.

Its kind of a hurry, need it within 1 hour and 50 minutes. THANKS A LOT! Would be the best help thanks!
