I keep on gettind errors that say "undefined var"! How do I define a var?? And I don't know what to do with this:


//I put together a little Wizard icon ( You can change it if you please )//
mob
Wizard//This makes a mob Called Wizard//
verb//This gives the mob/Wizard a verb//
Learn()//This Names the verb Learn//
set src in oview(1)
switch(input("Do you Want to Learn Fire Blast","?")in list("Yes","No"))//This asks the user in a input box if he/she wants to learn the spell Fire Blast and gives 2 choices Yes and No//
if("Yes")//This Will Do something if the user clicks Yes//
verbs+=new/mob/proc/Fire//This Adds the FireBlast verb to the users verb list//
if("No")
usr<<"Ok"
..()//This Calls Normal Action//



mob/Wizard
icon='Wizard.dmi'


They give me an error "mob/proc/FireBlast:undefined type path.

I'm such a newbie at Dream Maker please help!!!!
