Hi ahbyuan
I've never done this as such, but you may be able to adapt the following, which I've used to launch a 'pop-up' of a specific size from a control on another page.
In client-side jscript:
function popup(mylink, windowname) {
if (! window.focus)return true;
var href;
if (typeof(mylink) == 'string')
href=mylink;
else
href=mylink.href;
window.open(href, windowname, 'width=500,height=480,scrollbars=yes');
return false;
}
In html:
<a href="field_values.asp" onClick="return popup(this, 'info')"><img border="0" src="myicon.gif" width="23" height="24" align="top"></a>
HTH!
