Code:
encrypt(atom/ref,g)
        var/n=0
        var/t=0
        for(var/a in ref.vars)
            world<<ref.vars[a]
            if(isnum(ref.vars[a]))
                n++
                if(!(n%g))t/=n
                else t*=n
        return t

Most vars are a num, but isnum() isn't picking it up! Is there anyway to fix this?

Indeed; you have to stop assuming those vars are actually numbers. If isnum() says they aren't, they aren't. They're really a string or something else.

In response to Lummox JR (#1)
o.O
So vars are strings entirely?
Because I did:
mob
  var
    a=7
    j=9

And it should come out as numbers unless they get treated as text strings in the var list. :/

Simple work around:
var/Test=ref.vars[a]
if(isnum(Test))
