Sub with My variable

rodry has asked for the wisdom of the Perl Monks concerning the following question:

Here is the code in question

my $tabla = param("tabla"); if ($tabla eq "Miembros") { my $llave = MensajeMiembros(); } sub MensajeMiembros { my $email = param("email"); my $mensaje = "Blah Blah"; return ($email);

When I remove the my from $email it works as expected.

Replies are listed 'Best First'.

    if you write:
    if ($tabla eq "Miembros") { my $llave = MensajeMiembros(); }
    remember $llave is not visible outside the if() block; you should declare it before if you whant to use it outside:
    my $llave; if ($tabla eq "Miembros") { $llave = MensajeMiembros(); }

    is it possible that param is returning a list value rather than a scalar? If so,

    my $email = param("email");

    would fail, and you'd want to use

    my ($email) = param("email");
