All the solution I put are deemed incorrect

This is the second time that my initial code, that is correct, does not register as correct. This time, it is for the course Programming in R, Lesson 9, telegram.R. I put: telegram <- function(...){
  paste("START", ..., "STOP")
}
and it said it is incorrect. When I input the function skip(), it gave me the exact same code that I put.
