Validate First and Last name (not using regular expression)
<p>I need to validate user input of first and last name in the one input box. I have to make sure they only use letters and no other characters and is in uppercase or lowercase ex.. John Smith. I can find a lot of ways to do this using regular expressions, but the task has specifically asked that no regular expressions be used.</p>

<p>Even if someone to point me to where I can find this information myself.</p>

<p>Thanks </p>
