Subject: String Matching in an Array

I have an array set up that I want to match the user input to a property 
of a sting. However whenever I try to impliment the code the stings 
never match and I am returned nil.

The first two ways I tried:
class POlist
  def find(lookup)
    @purchase_orders.find { |aPOlist| lookup == aPOlist.po_number }
#    for i in 0...@purchase_orders.length
#      return @purchase_orders[i] if lookup == 
@purchase_orders[i].po_number
#    end
#    return nil
  end
end

and the other one:

found_one = false
print "Please Enter a PO: "
find_po = gets
for i in 0..aPOlist.length
  if aPOlist[i] == nil then break
  end
  if find_po.to_s == aPOlist[i].po_number
    found_one = true
    puts aPOlist[i]
  end
end
if found_one == false
  puts "PO NOT FOUND"
  menu_screen.root
end
