WoWInterface - Noob question on DK rune changes

I have an addon I am trying to update that would pull the rune count, by type and make spell suggestions based on what it found. I am trying to update this, to simply return the count for all of the runes (as the rune system changed). Would anyone mind helping me here? I took a crack at it, but it doesn't seem to be working :( Thanks for helping - I am fairly new to this.

New (not working):

Code:

local runes_c = {

    [1] = 0,

    [2] = 0,

    [3] = 0,

    [4] = 0,

    [5] = 0,

    [6] = 0

}



Goof.condition.register("runes.count", function(target, rune)

    local rune = string.lower(rune)

    runes_c[1], runes_c[2], runes_c[3], runes_c[4], runes_c[5], runes_c[6] = 0,0,0,0,0,0

    for i=1, 6 do

        local _, _, c = GetRuneCooldown(i)

        if c then

          runes_c[i] = runes_c[i] + 1

        end

    end

    return runes_c[1] + runes_c[2] + runes_c[3] + runes_c[4] + runes_c[5] + runes_c[6]

end)

Code:

local runes_t = {

    [1] = 0,

    [2] = 0,

    [3] = 0,

    [4] = 0

}

local runes_c = {

    [1] = 0,

    [2] = 0,

    [3] = 0,

    [4] = 0

Goof.condition.register("runes.count", function(target, rune)

    local rune = string.lower(rune)

    runes_t[1], runes_t[2], runes_t[3], runes_t[4], runes_c[1], runes_c[2], runes_c[3], runes_c[4] = 0,0,0,0,0,0,0,0

    for i=1, 6 do

        local _, _, c = GetRuneCooldown(i)

        local t = GetRuneType(i)

        runes_t[t] = runes_t[t] + 1

        if c then

            runes_c[t] = runes_c[t] + 1

        end

    end

    if rune == 'frost' then

        return runes_c[3] + runes_c[4]

    elseif rune == 'blood' then

        return runes_c[1] + runes_c[4]

    elseif rune == 'unholy' then

        return runes_c[2] + runes_c[4]

    elseif rune == 'death' then

        return runes_c[4]

    end

    return 0
