Hi,

I am using WWW::Mechanize to automate interaction with a web site. The user has to submit an order number and the web site will return a link to the order if the order exists.

My program is working fine under ideal conditions (i.e) if a link is returned by the web site.

But the program crashes if no link is returned by the web site and WWW::Mechanize returns " Can't call method "url" on an undefined value " error.

I read thru the documentation for the module in CPAN and it is mentioned that follow_link will return undef if no link is found.

I tested for undef and even then the program crashes.

Is there a way to overcome this problem and the program should output a user understandable error which i have give in the program.

Thanks in Advance!!!
