It will say that beacuse you haven't done the full script. You don't need the hidesprite 0x92. You've got a pointer leading to a branch that you haven't done yet.
Here is the script, just copy it up word for word. Give the pokeball an ID code of 0828. BTW, LASTTALKED means the last person you talked to.
