What I want to do is something like this:

searchid = 4

while searchid != -1

  @a += A.find(searchid)
  @b = B.find(searchid)
  searchid = @b.parentid
end

The problem being the line

@a += A.find(searchid)

The error being something like

NoMethodError: undefined method `+' for #

So, how do you combine multiple 'find' requests?
