View the script. This particular demonstration is designed as an error trap. To use the "throw" statement, you probably want to use a "try" and a "catch" also. If you deviate from the instructions in the prompt, with either a number lower than 1 or greater than 10, the script activates; it also activates if your entry is not a number. Otherwise, normally, if you follow the instructions, the page simply loads without incident. However, we have put in an alert to say that the option worked as it should have.
