ok my code looks like this

        
    mob/mugger
        icon = 'mugger.dmi'
        var
            wander = 1





        proc/Movement()
            if(wander) step_rand(src)
            ..()



And it says wander is undefined -__-

mob/mugger
    icon = 'mugger.dmi'
    var/wander = 1
    proc/Movement()
        if(wander) step_rand(src)
        ..()

Which works fine with no errors.

The code you just gave will compile. My guess is that you did something like this:

mob/verb/Rawr(mob/M in oview(5))
     M.wander = !M.wander //notice how M was defined as just a mob.
                          //it would give errors because the wander
                          //var is not defined under /mob
     if(!M.wander)
           view() << "[M] is so scared by [usr] that they stopped!"
     else
           view() << "[M] panicks because of [usr]'s roar!"


You could fix that by replacing mob/M with mob/mugger/M or by saying:

if(istype(M,/mob/mugger)) //this checks if they are of the /mob/mugger type
                          //or anything that descends from that type
       var/mob/mugger/MG = M //define a new var for the mugger


Or:

if(istype(M,/mob/mugger)) //same as before
      M:wander //you would access the vars with the : operator instead of the . operator
               //however, this can cause runtime errors if there is no wander var under M
               //Consider yourself warned!
