Michel's post shows how to remove the HTML tags, but if you want to show the tags that have been typed in, then before they post the string, surround the text input with < PRE > & < /PRE > tags, this can be done in the onsubmit event of the form :

<script>
function validate()
{
  document.all.fld1.value="<"+"pre>"+document.all.fld1.value+"</"+"pre>"
  return true
}
<script>

<form method="post" action="..." onsubmit="validate()">
<input type="text" id="fld1" name="fld1"></input>
<input type="submit" name="guestsubmit" value="Submit">Click to send
</form>

Note that you don't need to split the added tags ("<"+"pre>" & "<"+"/pre>") - thats due to a limitation of UT. You can also do other validation in the function (eg has user filled in all required fields) & if you don't want the form to be sent then return false

Also note, if your form is being submitted via a third-party CGI script (eg that of your ISP) you may find that they automatically strip any HTML tags from the incoming post for security reasons - mine does.
