this is the error i get when i try to use a code:

runtime error: Undefined operation
proc name: Bash (/mob/student/verb/Bash)
usr: Delita12345 (/mob/student)
src: the student (/mob/student)
call stack:
the student (/mob/student): Bash()

Here's the code snippet:

mob/student
icon = 'student.dmi'

var
M
health = 100
strength = 3
intel = 2
damage

verb/Chat(msg as text)
world << "[usr] says: [msg]"
verb/Break(obj/window in view(1))
icon_state = "broken"
verb/Bash() //THIS PART I'M HAVING TROUBLE WITH.
set src in oview(1)
damage = (usr/strength * 2) - src/intel
view() << "[usr] bashes [src] for [damage] points!"

Stat()
stat("health",health)
stat("Strength",strength)
stat("Intelligence",intel)
statpanel("Inventory",contents)
