I am wading into formulas within Spreadsheet::Write Excel. I am outputing rows of a database using $row++. However, I would like to use the data in certain columns using formulas thereby creating new columns in my spreadsheet output. However, the docs for Spreadsheet::WriteExcel isn't to detailed regarding this kind of formula syntax. Therefore, I am (once again) seeking the wisdom of the Perl Monks.
The Spreadsheet::WriteExcel syntax example: 
    my $formula = $worksheet->store_formula('=A1 * 3 + 50');

    for my $row (0..999) {
        $worksheet->repeat_formula($row, 1, $formula, $format, 'A1', '
+A'.($row +1));
    }

I've tried a number of variations on that theme but none have worked. Currently my version is: 
$worksheet->write_formula($row+2, 12, '=1-(K.($row+2)/J.($row+2))',$al
+ignPerc);

That code compiles but the output of the formula is always '1' (or 100%) which is not the right answer if I am successfully accessing the values in the adjacent columns. That implies my forumla is not correctly addressing the data in the other columns.
