Hi. I have a problem. I trying to write a program to do some stuff with excel, and I'm using SpreadSheet::WriteExcel. The problem, however, lies with the data structures somewhere, I think.

The number that follows TS is the test subject (identified by that number). Following that is the condition (one of 13). The data needs to be sorted by groups. There are three: low-hour vfr, low-hour instruments, and high-hour instruments (corresponding to certain test subjects; specifics in code). For these, I want to find the average for each condition, and display it in Excel.

This is the chunk that's giving me some problems. (the error in the tite)

` for(0..3) {
#here
($sums[$i])->[$_][$j] += $vals[$_+1];
if ($ts >= 21) {
$sums[$i]->[4][$j] += $vals[5];
$sums[$i]->[5][$j] += $vals[6];
}
}
#and here
$totals[$i]->[$j]->[0]++;
`

Here's the complete code to see how the ADTs evolve. (This is just a very preliminary 'test' to see what will work before I start doing some other things, but suggestions for better data types would be appreciated).

`#!/usr/bin/perl -w
use strict;
use Spreadsheet::WriteExcel;
my @groups = ([2,3,7,8,9,15,18,21,22,23,24,25,26,27],
# Low hour vfr, low hour instruments
[4,10,12,16,17,19], [1,5,6,11,13,14,20]);
# high hour instruments
my @cats = ('BL','BLSTDGG','PR1','PRFN1','PRFN3','PRFN30','EBG1',
'EBGFN1','EBGFN3','EBGFN30','CCFN1','CCFN30','CCFN30NT');

if ($ts >= 21) { $totals[$i]->[$j]->[1]++ }
my $col = 0;
for (@vals) {
$worksheet->write($row, $col, $_);
$col++;

$row++;
}
for my $r (0..2) {

}
}
my $format = [

I've worked with data dumper EXTENSIVELY, to a point where I'm pretty sure it has to do with the data STRUCTURE and not the data VALUES.
