I gave you TWO DIFFERENT WAYS of doing the copy.
The easiest, especially if you will only be using a handful of copied fields, is the version with the inline JS code, the stuff in post #48 and others. I do *NOT* suggest you use the copy(what) stuff at this time. If for no other reason than your instructor will never believe you wrote it if you don't understand it.
And no, I don't answer email questions about homework. (I do about other kinds of questions.) If I did (if any of us here did) we would be snowed under and never get any work done.
In any case, I'm off for the night. Food and sleep await me.
