    Ensure you don't have a JavaScript problem, essentially remove Perl from the equation by testing that the HTML it generates works. Use something like FireBug to debug. Consider using templates (HTML::Template, Template::Toolkit) to seperate your perl code and HTML/CSS/JS.

    but its not working as expected

    Really? It's working exactly how I'd expect it to (i.e. not at all). If it's not working how you'd expect it to, then change your expectations.

    Go back to square one. Learn how the Web works. In particular pay attention to the distinction between client-side and server-side scripting.

    Think of it this way. My name is Mr Server; your name is My Browser. We live in different towns. We can talk on the telephone, but if I'm eating a bacon sandwich while we're talking, you can't smell it.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

    What kind of beast this Update_database is? Is it a javascript function?
[reply]
      no its just a perl function
[reply]
        The code specified in an onClick event is not Perl code. Perk runs on the server, for client-side scripting, Javascript is usually used.
