Help needed...js error

[Ed Jay]

This is part of another quest for solution I've posted, but I'm getting no
responses.

My script is:

var popwin;
function launchwin(winur l,winname,winfe atures) {
if (popwin) {popwin.close() ;}
popwin = window.open(win url,winname,win features);
popwin.focus();
}

URL: http://www.edbj.itnava.com/brca.html

This works...to an extent. If the window launched is manually closed, and
then an attempt is made to re-open the window, the script fails with the
error: 'Type mismatch (usually a non-object value used where an object is
required) -- if (popwin).' The only way to re-use the function a second
time is to reload the page.

Help! Please... Thanks in advance.

Solution: Use
try {popwin.close() ;} catch(e) {};
instead of
if (popwin) {popwin.close() ;}
