Yeah, that's what happens, if you don't try out what you've posted. :-)

[snip]
function cpn() {
  setopt localoptions
  setopt globassign
  local nf nd
  [[ -z ${1} || -z ${2} ]] && printf 'usage: cpn <fromdir> <todir>\n' && return 1
  nf=${1}/*(.om[1]N)
  nd=${2}/*(/om[1]N)
  [[ -n ${nd} && -n ${nf} ]] && command cp ${nf} ${nd}
}
[snap]

That should work better.
