creating/using libraries Perl...blank outout?

Good morning!!

Im trying to create a script that should get a list of numbers from the user (using STDIN or a list of arguments), and call my library function.
Code:
#!use/bin/perl

require 'my-lib.pl';
@userArray = <STDIN>;

while()
{
chomp;
last if ! /\d/;
push(@userArray,&_);
}
($sum,$avg) = $sumIt(@userArray);

print "Total:$sum\nAverage\n:$avg\n";

Im my library it should contain a function that takes in an array of numbers, then the function will calculate the average of the numbers, the total of the numbers and a new array of numbers which is divided by 2. The new list will contain all this information.

My library:
Code:
sub sumIt {
my @functionArray = @_;
forwach my $line(@functionArray){
$functionSum += $line;
$count++
}
return ($sunctionSum,$functionSum / $count);
}
1:

But it doesnt return anything to help me. No errors, nothing. It appears to hang?

Any help with this will be greatly appreciated!

MicroMason::TextTemplate(3pm)				User Contributed Perl Documentation			     MicroMason::TextTemplate(3pm)

NAME
Text::MicroMason::TextTemplate - Alternate Syntax like Text::Template SYNOPSIS
Instead of using this class directly, pass its name to be mixed in: use Text::MicroMason; my $mason = Text::MicroMason::Base->new( -TextTemplate ); Use the standard compile and execute methods to parse and evalute templates: print $mason->compile( text=>$template )->( @%args ); print $mason->execute( text=>$template, @args ); Text::Template provides a syntax to mix Perl into a text template: { my $hour = (localtime)[2]; my $daypart = ( $hour > 11 ) ? 'afternoon' : 'morning'; '' } Good { $daypart }, { $name }! DESCRIPTION
This mixin class overrides several methods to allow MicroMason to emulate the template syntax and some of the other features of Text::Template. Compatibility with Text::Template This is not a drop-in replacement for Text::Template, as the Perl calling interface is quite different, but it should be able to process most existing templates without major changes. This should allow current Text::Template users to take advantage of MicroMason's one-time compilation feature, which in theory could be faster than Text::Template's repeated evals for each expression. (No benchmarking yet.) Contributed patches to more closely support the syntax of Text::Template documents would be welcomed by the author. Template Syntax The following elements are recognized by the TextTemplate lexer: o literal_text Anything not specifically parsed by the below rule is interpreted as literal text. o { perl_expr } A Perl expression to be interpolated into the result. Good { (localtime)[2]>11 ? 'afternoon' : 'morning' }. The block may span multiple lines and is scoped inside a "do" block, so it may contain multiple Perl statements and it need not end with a semicolon. Good { my $h = (localtime)[2]; $h > 11 ? 'afternoon' : 'morning' }. To make a block silent, use an empty string as the final expression in the block. { warn "Interpreting template"; '' } Hello there. Although the blocks are not in the same a lexical scope, you can use local variables defined in one block in another: { $phase = (localtime)[2]>11 ? 'afternoon' : 'morning'; '' } Good { $phrase }. Argument Passing Like Text::Template, this package clobbers a target namespace to pass in template arguments as package variables. For example, if you pass in an argument list of "foo => 23", it will set the variable $foo in your package. The strict pragma is disabled to facilitate these variable references. Internally, this module inherits this functionality from the PassVariables mixin. If you are using the TextTemplate mixin, do not also specify the PassVariables mixin or it will be included twice. For more information, see Text::MicroMason::PassVariables. Supported Attributes package Target package namespace. Private Methods prepare() If a package has not been specified, this method generates a new package namespace to use only for compilation of a single template. lex() Lexer for matched braces - produces only text and expr tokens. Uses Text::Balanced. SEE ALSO
The interface being emulated is described in Text::Template. For an overview of this templating framework, see Text::MicroMason. This is a mixin class intended for use with Text::MicroMason::Base. For distribution, installation, support, copyright and license information, see Text::MicroMason::Docs::ReadMe. perl v5.10.1 2007-01-29 MicroMason::TextTemplate(3pm)
