Does anyone know how to adapt the following script so that it works with 2 checkboxes and 2 layers, all hidden until a checkbox is selected.   If the other checkbox is selected the layer should hide,with the other becoming visible.


<html>
<body>
 
<input id="inp1" onclick="ToggleVisibility();" type="checkbox" checked="true" >Show DIV</input>
<br/>
 
<div id="div1" style="background-color:#aaaaaa;font-size:20pt;">
Hello World!
</div>
 
<script>
 
function ToggleVisibility()
    {
    var objInp = document.getElementById("inp1");
    var objDiv = document.getElementById("div1");
 
    if (objInp.checked) objDiv.style.visibility = ""; else objDiv.style.visibility = "hidden";
    }
 
</script>
 
 
</body>
</html>

If you can only have 1 visible at a time, might be better to use a radio group
