hi tilly,
i have been trying to tweak the script you wrote to cover one more aspect of what i am doing - i need to search for all rows that have a particular id, not just the first one. here's where the script is: 
open FILE , "/courses.txt" or die "Cannot open: $!";

my $couvalue = param('name');
my $courowid = $ARGV[0] || $couvalue;
my %coudata = ();
my @coufields = split(/\t/, <FILE>);
chomp @coufields;


while(<FILE>) {
    chomp;     
    my @courow = split(/\t/);
    if ($courow[0] eq $courowid) {
        @coudata{@coufields} = @courow;
        last;
    }        
}

close (FILE);


print header;
if ( keys %coudata ) {
    # found, display data
    print ul( map { li("$_: $coudata{$_}") } keys %coudata);      
}
else {
    # not found, show error
    print h1("Can't find row '$courowid'");
}



#######this is what the table looks like:

1414    "Nutitional Epidemiology"
1414    "Nutritional assessment"
1414    "Undernutrition in the United States"
1371    "Health Politics and Policy"
1371    "Advanced Health Politics?"
1371    "Introduction to Health Policy & Management"
1371    "Health and Public Policy Seminar"

i only get one row back.
i've tried taking out "last;"
i've tried to do a foreach instead of an if, but i can't get it to work. i've even posted another sopw, in trying to use "push" to get all the lines that match into one array.
i wanted to ask you if this script can work for this problem, and if so, where should changes be made.

thank you for your help.
