I suspect that the problem is with the deletion from an array within a loop
of that array.

Solution: construct a different array such that => if ow != 'no' then
new_array.push(x); end;

consider the following test.

irb(main):013:0> x = [1,2,3,4]
=> [1, 2, 3, 4]
irb(main):014:0> x.each { |ii|
irb(main):015:1*   print "ii = #{ii}\n"
irb(main):016:1>   print "x = #{x}\n"
irb(main):017:1>   x.delete(ii)
irb(main):018:1>   print "x now = #{x}\n"
irb(main):019:1> }
ii = 1
x = 1234
x now = 234
ii = 3
x = 234
x now = 24
=> [2, 4]


While this does not demonstrate your issue persay, it does however
illustrate a bug.  ii never equals the value of the original second index,
because the array's iterator does not go back a step on deletion.

Hope this helps.
