building arrays and comparing the contents

Hi team,

building a flash drag and drop activity with a check answers button, having trouble getting the arrays to compare.. here is my code (below)

why wont my uanswer array work properly and when I compare arrays how can I get them to "match" or == if they have the same contents in different order? Does it matter?

Also  can I get a number reutrned on how many matching items there are even if they dont completely match?

Cheers
