RevScripts Elemental damage problem TFS 1.3

[Icaraii]

Guys, I'm with a little problem that I've being breaking my head and no solution is coming out.
My server is a custom server with only one class and 9 types of weapons that the player can change between weapons and doing so the player will change his gameplay.
Close combat weapons use sword skill and distance combat weapons use distance skill, also my server is greatly influenced by the 7 elements (physical, energy, earth, fire, ice, holy and death).

The problem begins when I try to add elemental damage to weapons:
If I use

<attribute key="elementIce" value="110" />

in item.xml I also have to use at least 1 attack

<attribute key="attack" value="1" />

If I don't do that, the weapon doesn't show it's damage. But doing that add a bug to my client, where different types of damage stack on top of each other, becaming impossible to see how much damage the player is doing.
Trying to solve the client bug I try to use a weapon script to add damage to weapons:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, 1)

function onGetFormulaValues(player, skill, attack)

    local playlvl = player:getLevel()
    local sword = player:getSkillLevel(SKILL_SWORD)

    if (playlvl<300) then
    local min = ((((attack * 150000) / 5000) * ((attack * sword * 25000) / 2000) * (attack * player:getLevel() * 13000 / 3000)) / 100000000000)
    local max = ((((attack * 150000) / 5000) * ((attack * sword * 25000) / 2000) * (attack * player:getLevel() * 13000 / 3000)) / 100000000000) * (((attack * attack) * 2) / 2000)
    return -min, -max
    
    else
    local min = ((((attack * 150000) / 5000) * ((attack * sword * 25000) / 2000) * (attack * player:getLevel() * 13000 / 3000)) / 100000000000)
    local max = ((((attack * 150000) / 5000) * ((attack * sword * 25000) / 2000) * (attack * player:getLevel() * 13000 / 3000)) / 100000000000) * (((attack * attack) * 2) / 2000)
    end   
end                             

combat:setCallback(CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")
            
 
local area = createCombatArea( { {0, 0, 0}, {0, 3, 0}, {0, 0, 0} } )
setCombatArea(combat, area)
 
function onUseWeapon(cid, var)
        return doCombat(cid, combat, var)
 

end

The problem now it's that only works in elemental weapons. If I leave only the attack in items.xml it doesn't do any damage with this script. And now I don't know how to proceed to solve the problem.

More information:
Item.xml:

    <item id="26803" article="an" name="Iron Revolver">
        <attribute key="weight" value="2100" />
        <attribute key="attack" value="100" />
        <attribute key="weaponType" value="distance" />
        <attribute key="shootType" value="explosion" />
        <attribute key="range" value="7" />
</item>
    <item id="26805" article="an" name="Promise Of Destruction">
        <attribute key="weight" value="2200" />
        <attribute key="attack" value="50" />
        <attribute key="weaponType" value="wand" />
        <attribute key="shootType" value="smallearth" />
        <attribute key="range" value="7" />
</item>

    <item id="2214" article="an" name="Of Destruction">
        <attribute key="weight" value="2200" />
        <attribute key="attack" value="1" />
        <attribute key="elementIce" value="110" />
        <attribute key="weaponType" value="distance" />
        <attribute key="shootType" value="explosion" />
        <attribute key="range" value="7" />
</item>

I've tryed all the ways above and none of them solved my problem.

weapons.xml:

    <distance id="2214" level="20" type="ice" event="function" value="default" action="removecharge" range="8">
    </distance>
    
    <distance id="26803" level="130" unproperly="1" action="removecharge" range="8" script="distanceweapon.lua">
    </distance>
    
    <distance id="26805" level="140" action="removecharge" range="8" script="distanceweapon.lua">
    </distance>

With all I explained of my server, does anyone have a solution?

does anyone have any ideia to what I could do?

function onGetFormulaValues(player, skill, attack)

You actually have to return the min, max from the function, or you will get no damage.

function onGetFormulaValues(player, skill, attack)
    local min = math.max(attack - 10, 1)
    local max = attack + 10
    return -min, -max
end

 

[Icaraii]

return -min, -max

I can't believe I forget about that line... I had it on, but I erase it when I was making the formula and forgot the put it back. Thanks for the eagle eyes.
