Hi. My name's Ang and I'm new (to perlmonks and to Perl, first computer programming class) and I need help with a homework assignment. This is my homework assignment:

Consider a file consisting of lines that contain a color and an amount separated by colons, like:

red:27

yellow:102

green:311

yellow:12

blue:45

Should output (not necessarily in that order):

red:27

yellow:114

green:311

blue:45

Your program must take the input file as a parameter.

This is the code I've written:

#!/usr/bin/perl;
use strict;
use warnings;

open (FH,$ARGV[0]) or print "could not open file" ;
my $info = <FH>;


while ($info=~ /(\w+ (-?\d+ )+)/)
{
        my $info =~ s/(\w+ (-?\d+ )+)//;
}

my @nums = split(/:/,$info);
my $word = shift (@nums);
my $sum = 0;
my $var = ($info);

foreach $var (@nums)
{
    $sum = $sum + $var;
}


my %hash = ($word = $sum);

print @nums;


close(FH);

These are the errors I'm getting.. and I don't understand them, how to fix them.. I feel like I'm not that good at this, so if you decide to help me explain it like I'm a kindergardener..

Argument "27 yellow" isn't numeric in addition (+) at ar991homework411 line 21, <FH> line 1. Argument "102 green" isn't numeric in addition (+) at ar991homework411 line 21, <FH> line 1. Argument "311 yellow" isn't numeric in addition (+) at ar991homework411 line 21, <FH> line 1. Argument "12 blue" isn't numeric in addition (+) at ar991homework411 line 21, <FH> line 1. Odd number of elements in hash assignment at ar991homework411 line 25, <FH> line 1.

Thanks for any help! Ang
