Meaning I should define it before going to the
subroutine itself ? I really dunno this.

Well, I'm calling $se{searchengine} where
'searchengine' is the input taken from the user in
webpage. User choose the search engine from the
dropdown list.Options are Yahoo with value 'yh',
AltaVista 'av' and Google 'gg'.
> Why do you call the subroutine only once?
Do I have to call it many times in a loop. Once user
goes back to search, it a brand new search, right?
Correct me if I 'm wrong but basically I want to read
the input from the dropdown list and process the
search.
Thank again for your attention.Pls correct me.
