Firstly, Why did you put your question in a code block, doesn't look very clever............ Ok, so back to your question; You can use the object onChange to call a javascript function to validate the content as each element changes. You could also use a button when you submit to check each element. The code below is a sample to help you get going, but there are heaps of examples on the net. You could take all the javascript out of the lower script block and place it in a reference file as shown in the upper script block entry

<script type="text/javascript" src="js/thejsfile.js"></script>

</head>
<body>

<table>
    <tr><td>Name:</td><td><input id="textName" type="text" onchange="validateName()"/></td><td id="nameValidMessage"></td></tr>
    <tr><td>Age:</td><td><input id="textAge" type="text" onchange="validateAge()"/></td><td id="ageValidMessage"></td></tr>
</table>
<input id="ButtonGo" type="button" value="Go" onclick="go\_click()"/>
<script type="text/javascript">

    function validateAge() {
        var valid = false
        //write you code to validate the age
        //set valid to true if all ok

        if (textAge.value == "99") { valid = true; }

        //update the page message
        if (!valid) {
            ageValidMessage.innerHTML = "Invalid Age";
        }
        else {
            ageValidMessage.innerHTML = "";
        }

        return valid
    }

    function validateName() {
        var valid = false
        //write you code to validate the name
        //set valid to true if all ok

        if (textName.value == "Dave") { valid = true; }

        //update the page message
        if (!valid) {
            nameValidMessage.innerHTML = "Invalid Name";
        }
        else {
            nameValidMessage.innerHTML = "";
        }

        return valid
    }

    function go\_click() {
        var valid
