Shandy, Perhaps this helps.  Note the difference between 004 and 006

irb(main):003:0> i = "1234"
=> "1234"
irb(main):004:0> i[0]
=> 49
irb(main):005:0> i[0].class
=> Fixnum
irb(main):006:0> i[0,1]
=> "1"
irb(main):007:0> i[0,1].class
=> String
irb(main):008:0> i[0,1].to_i
=> 1
irb(main):009:0> i[0,1].to_i.class
=> Fixnum


Good luck from another newbie.
Ian
