Thanks kevin,
I read modules and wrote the following script:
my $popup = $ie->getPopupWindow("Request Acknowledged-Phaser 4510DT");
$popup->getTable('id:', "headingtext")->Click;

When i use this in my script i am getting error like this:
-Use of uninitialized value $counter in numeric le(<=) at E:/Perl/site/lib/win32/IEAutomation.pm line 537
-Can't call method "title" on an undefined value at E:/Perl/site/lib/win32/IEAutomation.pm line 542.

please give me some suggestions on how to get rid of this error
