Lua How to properly code formulas into a config section

[aalqaq2]

TFS 1.3
I need to know how to code

local min = (level / 5) + (maglevel * 4.3) + 32
local max = (level / 5) + (maglevel * 7.4) + 48

into

local config = {
     damage = {-min, -max},
}

Here's the rest of the code.

function doAreaCombatDamage(cid, attacker, combatType, position, min, max, effect)
     local creature = Creature(cid)--// Incase the creature disappears within 120-250ms time window
 
     if not creature then
        return
     end
 
    doAreaCombatHealth(attacker, combatType, position, 0, min, max, effect)

end

    local running = {}

local function runSpell(cid, i, j, delay, radius, damage, damageType, areaEffect, distanceEffect)
     local player = Player(cid)--// Player doesn't exist anymore
     if not player or Tile(player:getPosition()):hasFlag(TILESTATE_PROTECTIONZONE) and bit.band(player:getGroup():getFlags(), PlayerFlag_IgnoreProtectionZone) == 0 then
         stopEvent(running[cid])
         running[cid] = nil
         return
     end

    if i > j then--// Maximum rounds complete
        stopEvent(running[cid])
        running[cid] = nil
        return
end

    local center = player:getPosition()
    local specs = Game.getSpectators(center, false, false, radius.x, radius.x, radius.y, radius.y)
    local args = {nil, cid, damageType, nil, damage.min, damage.max, areaEffect}--// Send effects and damage creatures within radius
     for i = 1, #specs do
         if specs[i]:isMonster() then
         local specPos = specs[i]:getPosition()
         args[1] = specs[i]:getId()
         args[4] = specPos
         center:sendDistanceEffect(specPos, distanceEffect)
         addEvent(doAreaCombatDamage, 120 + (center:getDistance(specPos) * 7), unpack(args))
        end
    end
        addEvent(runSpell, delay, cid, i+1, j, delay, radius, damage, damageType, areaEffect, distanceEffect)
end

    local offsets = {DIRECTION_WEST, DIRECTION_NORTH, DIRECTION_EAST, DIRECTION_SOUTH}
    local function sendEffects(cid, delay, areaEffect, distanceEffect)
    local player = Player(cid)

    if not player or Tile(player:getPosition()):hasFlag(TILESTATE_PROTECTIONZONE) and bit.band(player:getGroup():getFlags(), PlayerFlag_IgnoreProtectionZone) == 0 then
        stopEvent(running[cid])
        running[cid] = nil
        return
    end

        local pos = player:getPosition()
         for i = 1, #offsets do--// Send distance effects (N/E/S/W) & area effect on player
               local fromPos = pos:setDirectionOffset(offsets[i])
               local fromPos = pos:setDirectionOffset(player:getPosition())
               local toPos = pos:setDirectionOffset(offsets[i+1] or offsets[1])
  fromPos:sendDistanceEffect(toPos, distanceEffect)
         end
 
        pos:sendMagicEffect(areaEffect)
        running[cid] = addEvent(sendEffects, delay, cid, delay, areaEffect, distanceEffect)
end

local config = {
    damage = {min = -68, max = -136}, -------THIS IS THE LINE I WANT TO CHANGE
    rounds = 30, -- number of times the spell loops (effects & damage)
    delay = 320, -- ms
    radius = {x = 5, y = 5}, -- sqm radius
    damageType = COMBAT_DEATHDAMAGE,
    areaEffect = CONST_ME_MORTAREA,
    distanceEffect = CONST_ANI_DEATH,
}

function onCastSpell(cid, creature, variant)
    local player = Player(cid)
    if not player then
        return false
    end
 
    sendEffects(player:getId(), config.delay, config.areaEffect, config.distanceEffect)
    runSpell(player:getId(), 0, config.rounds, config.delay, config.radius, config.damage, config.damageType, config.areaEffect, config.distanceEffect)
     return true
end

The closest I could get was the spell working but no damage being dealt.
