Can't create 2d array in Perl

Hi:
I would like to read a tab delimited text file created in Excel into a 2d array. I don't understand why the following doesn't work. The $i and $j, along with the print statement, are only for debugging purposes.
It prints:
Can't use string ("") as an ARRAY ref while "strict refs" in use at file_vars.pl line 30, <FH> line 2.

*********************************************************
#!/usr/bin/perl -w
use strict;
my @arr ;
my $i = $ARGV[0];
my $j = $ARGV[1];
print $i . " \t" . $j . "\n";
open(FH,"<0817L.txt") or die "cannot open !$\n";
while(<FH>)
{
push @arr , split /\t/ ;
}
print $arr[$i][$j];
.
