My task is to login to www.gmail.com and then select the checkbox corresponding to first mail and delete. However, I am unable to select the checkbox. Here is my snippet:

use Win32::IEAutomation;
use Data:Dumper;
$\="\n";
$,=" ";

open FH, ">D:/material/Perl_ppts/test.txt" or die $!;

$ie=Win32::IEAutomation->new(visible=>1, maximize=>1);

$url='https://www.google.com/accounts/ServiceLogin?

service=mail&passive=true&rm=false&continue=http://mail

.google.com/mail/%3Fui%3Dhtml%26zy%

3Dl&bsv=1eic6yu9oa4y3&scc=1&ltmpl=default&ltmplcache=2
';


$ie->gotoURL($url);

$ie->getTextBox('id:', 'Email')->SetValue

('<userid>');
$ie->getTextBox('id:', 'Passwd')->SetValue

('<password>');
#print $ie->PageText();

$ie->getButton('id:', 'signIn')->Click;
print Dumper($ie->URL());

$ie->getCheckbox('id:',':nu')->Select; #Failed
#then i tried this->
$ie->getCheckbox('index:', 1)->Select; #FAILED
