Every if statement has to have an 'end'. Right now you've got more
if's than end's. It's because you're using this:

   else
     if

(with no 'end' for the if) instead of:

   elsif

They're both OK, but if you use the first one, you're starting a new
if and it has to have its own end.

Compare these two:

   if x
     puts "x is true"
   elsif y
     puts "y is true"
   else
     puts "Neither is true"
   end

   if x
     puts "x is true"
   else
     if y
       puts "y is true"
     else
       puts "Neither is true"
     end
   end

You're doing something like the second, but without matching if/end.
