Nostalrius Begins - Quality wow vanilla realm (1.12)

I've found that trying to use macros provided on this page: https://forum.nostalrius.org/viewtopic.php?f=44&t=1440

More specifically, the shift to cast rank one spells. Could someone help me with this? I just get an error message of some kind.

Seen this below the macros?
