Alert Message/onClick - EASY POINTS

I need assistance with the following function.


<script language="JavaScript">
<!--
function checkFields() {
var form = document.forms[0];  
if ((form.RadialButton.value == "Yes")) {
alert("Message to display onClick.")
return false;
}
else {
return true;
}
}
// -->
</script>


<input type="radio" name="RadialButton" value="Yes" onClick="return checkFields()">


When a user clicks this radial button, I have an onClick event calling this function, which displays
the message, which is what I need.  But after the user hits OK from the alert, I need the radial button
to stay selected and allow them to continue through the form.  Currently, I select the radial button,
get the message, hit OK, then the radial button is unselected.  If I try to select it again it does
the same thing.  I know I am missing some other command to let the user pass after they have hit OK
from the message, but I have been unable to figure it out.  Time is of the essence.  (points added for
quick response)  Please assist.  Thank you.

Change it to this

<script language="JavaScript">
<!--
function checkFields() {
var form = document.forms[0];  
if ((form.RadialButton.value == "Yes")) {
alert("Message to display onClick.")
return true;
}
else {
return false;
}
}
// -->
</script>

returning false cancels the event which triggered the code

I think that this works the way that you want it to:

<SCRIPT LANGUAGE=javascript>
<!--

function checkFields()
{
//var form = document.forms[0];
for (count=0; count<2; count++)
     {
     if(form.RadialButton[count].checked)
          {
          //alert(count);
          strValue =form.RadialButton[count].value;
          if(strValue=="Yes")
               {
               alert("This is the onClick Message!")
               return false;
               }
          else
               {
               return true;
               }
          }
     }    
}
// -->
</script>

Sorry,

Here's the whole thing:

<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">
<TITLE></TITLE>
<SCRIPT LANGUAGE=javascript>
<!--

function checkFields()
{
//var form = document.forms[0];
for (count=0; count<2; count++)
     {
     if(form.RadialButton[count].checked)
          {
          //alert(count);
          strValue =form.RadialButton[count].value;
          if(strValue=="Yes")
               {
               alert("This is the onClick Message!")
               return false;
               }
          else
               {
               return true;
               }
          }
     }    
}
// -->
</script>
