same directory of the program.
my code:

require 'parseexcel'

workbook = Spreadsheet::ParseExcel.parse('2007-02-231028.xls')

worksheet = workbook.worksheet(0)

skip = 2
worksheet.each(skip) { |row|
# a row is actually just an Array of Cells..
first_cell = row.at(0)

}

Error is:
undefined method `at' for nil:NilClass
