I am getting this error when reading an XL file.

Character in 'c' format wrapped in pack at c:/Perl/site/lib/Spreadsheet/ParseExcel.pm line 1789.
Character in 'c' format wrapped in pack at c:/Perl/site/lib/Spreadsheet/ParseExcel.pm line 1790.

Here is a sample record.
There are more cells but for formatting reasons I removed them though the data is the same.

18 56.04 61.64 67.25 72.84 78.45 84.06 89.66 95.27 100.86

Thank you in advance.
