  1. Create a JavaScript function that will collect the information from the form and verify that it is the correct type and that there are no blank textboxes.

  2. Save and test the file to ensure that the textbox information is collected and the script is working correctly.

  3. Use the onclick event within the submit button to call this function.

  4. Output validation error messages by writing directly to the

    with the id of "results."

    • (You may want to use alert boxes for testing at first. If you do this, remove the alerts and ensure the message is displayed correctly before submitting.)

  5. Create a loop within the above function that collects the checked value of the radio button group.

  6. Once the value from the radio group is collected,

    • create a function to pass the value for evaluation and return a message for the user based on his or her selected skill type using the

      with the id of "more."
