Hi, I'm having a problem with the assignment of multidimensional hashes: 
$i=0; $j=0;
while (<FIRE>) {
chomp $_;
($fgid[$i], $fvalue, $flat[$i], $flong[$i]) = split /,/, $_;
$fval{$flat[$i]}{$flong[$i]}=$fvalue;
$i++;
}

The input data looks like this 
virsfire_199801,-1,39.750000,-179.500000
virsfire_199801,-1,39.750000,-179.000000
virsfire_199801,-1,39.750000,-178.500000
virsfire_199801,-1,39.750000,-178.000000

I'm trying to index fvalue with its latitude and longitude values. Something goes wrong though. For example, when I insert 
print "testing: $flat[1], $flong[1]\n";
print "testing: $fval{39.750000}{-179.000000}\n";
print "testing: $fval{$flat[1]}{$flong[1]}\n";

I get the following output: 
# ./join.pl 
testing: 39.750000, -179.000000
testing: 
testing: -1

It seems as if I'm not indexing on the numerical values, but rather on the variable names. Why is this? Thank you, oh monks.
