Any sugguest for java script check form

heres a javascript form from this page.

<script language="JavaScript"> function CheckForm() {  var errorMsg = ''; //For Gecko Madis API (RTE) if (document.frmAddMessage.message.value.indexOf('<br>') > -1 && document.frmAddMessage.message.value.length == 8) document.frmAddMessage.message.value = ''; //Check for message if (document.frmAddMessage.message.value==''){ errorMsg += '\n\tMessage Box \t\t- Enter a Message to Submit'; } //If there is aproblem with the form then display an error if (errorMsg != ''){ msg = '_______________________________________________________________\n\n'; msg += 'The form has not been submitted because there are problem(s) with the form.\n'; msg += 'Please correct the problem(s) and re-submit the form.\n'; msg += '_______________________________________________________________\n\n'; msg += 'The following field(s) need to be corrected: -\n'; errorMsg += alert(msg + errorMsg + '\n\n'); return false; } document.frmAddMessage.Submit.disabled=true; return true; } </script>

just change the names for the form (frmAddMessage) and make sure the name for the message field (message) in the above example is correct.

Using the js and form shown below The validation Alert shows correctly but when OKing the alert the form submits to the next page. If the RTE isn't installed and only a text box is used  the validation works perfectly.   I do see that it works on the board here, am I missing  something simple?

<script  language="JavaScript">
<!-- Hide from older browsers...

//Function to check form is filled in correctly before submitting
function CheckForm () {
   
    var errorMsg = "";
   
    //Check for an News Title
    if (document.frmNews.title.value==""){
        errorMsg += "\n\tTitle \t\t- Enter a title for the News Item";
    }
   
    //Check for an News Title
    if (document.frmNews.shortNews.value==""){
        errorMsg += "\n\tShort News \t- Enter a Short News Item to display";
    }
   
    //Check for news Item
    if (document.frmNews.newsItem.value==""){
        errorMsg += "\n\tNews Item \t- Enter a News Item to post";
    }
   
    //If there is a problem with the form then display an error
    if (errorMsg != ""){
        msg = "____________________________________________________________________\n\n";
        msg += "Your News Item has not been submitted because there are problem(s) with the form.\n";
        msg += "Please correct the problem(s) and re-submit the form.\n";
        msg += "____________________________________________________________________\n\n";
        msg += "The following field(s) need to be corrected: -\n";
       
        errorMsg += alert(msg + errorMsg + "\n\n");
                return false;
    }

    document.frmNews.Submit.disabled=true;
    return true;
}
// -->
</script>


and this form:

<form method=post name="frmNews" action="WWN_add_news.asp" onSubmit="return CheckForm();" onReset="return ResetForm();">

Good luck. I worked for a while on  it with resolution to the problem. It was easier in the end to let the form submit and do the verification with asp on the next page.  It works here so there is probably a simple solution. Not one that I could see though
