I tried to run this script and get the error

"Error at line 22
Line text: ^-::ClonesPush("{- down}{- up}")
Error hotkeys/hotstrings are not allowed inside functions.
This program will exit.
"

All I did was copy paste it from the wiki! (and I deleted the references to the last 3 wows, since I'll only be running it dual boxing)
