Hello,
To create a popup you'll need the following script:
<script language="javascript" type="text/javascript">
<!--
function popitup(url) {
newwindow=window.open(url,'name','height=200,width =150');
if (window.focus) {newwindow.focus()}
return false;
}
// -->
</script>
Then, you link to it by:
<a href="popupex.html" onclick="return popitup('popupex.html')"
>Link to popup</a>
