Referring to an array from within an array

How do i refer to an array name inside an array?
This is what i have:
array1 = [“test1”, “test2”, array2];

array2 = [“bla”,“bla”,“succes”];

Now i need something like stuff=array1[3]; (this makes an array called stuff which is a copy of array2, hopefully) and then myvar=stuff[3] (which is “succes”)… get it? no this doesnt work and i dont know why :frowning: could someone help me?
