<p>This is may code so far. I would like the FIRST_Name and LAST_Name fields to capitalize the first letter and have all other letters small:</p>

<p>Also, I am unfamiliar with javaScript so I am not exactly sure what I am doing.</p>

<p><strong>latest edit. What is wrong with this code?</strong></p>

<pre><code>    &lt;HTML&gt;
&lt;HEAD&gt;
&lt;TITLE&gt;&lt;/TITLE&gt;
&lt;script language="javascript" type="text/javascript"&gt;
&lt;!--
function CheckForm()

formObj.FIRST_Name.value = titleCase(formObj.FIRST_Name.value);
formObj.LAST_Name.value = titleCase(formObj.LAST_Name.value);

function titleCase(str) {
    var words = str.split(/\s+/);
    for (var i=0; i&lt;words.length; i++)
        words[i] = words[i].charAt(0).toUpperCase() + words[i].slice(1);
    return words.join(" ");
}


{
  var formObj = document.getElementById("Data");
  var firstname = formObj.FIRST_Name.value;
  var lastname = formObj.LAST_Name.value;


    if(notEmpty(formObj.FIRST_Name, "Please enter your first name")){       
    if(notEmpty(formObj.LAST_Name,"Please enter your last name")){  
    if(titleCase(formObj.FIRST_Name)            

    return true;}}

    return false;
    }

function notEmpty(elem, helperMsg){
    if(elem.value.length == 0){
        alert(helperMsg);
        elem.focus(); // set the focus to this input
        return false;
    }
    return true;
}


&lt;/script&gt;
&lt;/HEAD&gt;
&lt;BODY&gt;
&lt;div style="background: #CCCC99"&gt;
&lt;HR&gt;&lt;FORM id="Data" onsubmit="return CheckForm()" action="post to server" method=post&gt;
&lt;P&gt;First Name: &lt;input type=text name=FIRST_Name maxlength=15 size=15&gt;
   Last Name:  &lt;input type=text name=LAST_Name maxlength=15 size=15&gt;&lt;/P&gt;
&lt;input type=submit value="Submit Products Registration Form" style="width: 220px"&gt;&lt;input type=reset value="Reset"&gt;
&lt;/form&gt;
&lt;/div&gt;
&lt;/BODY&gt;
&lt;/HTML&gt;
</code></pre>
