Subject: less absolutely horrible way to make sure array 1 only contains elements from array 2?

@selections = []
sane = 0
while sane == 0 do
print "Make selections: "
myselections = gets.chop.split(" ")
myselections.each do |path|
@selections.push(path)
end
@selections.each do |selection|
choices.each do |choice|
if choices == selections then sane +=1
end
if sane != @selections.length then
puts "One of the selections is not available"
sane = 0
@selections = []
end
end
end
end

I need to make sure that myselections only contains elements from
choices, includes? doesn't work because it allows for partial matches.
This works but it looks absolutely horrible.
