Hi Puneet,
Thanks for your/everybody's help. I had to
edit the Template file ( i.e the htm file in linux,
instead of in the frontpage editor ), and with the
correct syntax provided by everyone on this list I
could get this thing working ( $template->param(lname1
=> "xyz" );.
The @paramteres = $template->param();
returns the parameters which are defined in
the template file. So in my case it returned lname1.
Thanks,
Girish
