in other script

function onHealthChange(creature, attacker, primaryDamage, primaryType, secondaryDamage, secondaryType, origin)
local hp = math.random(2000,7500) 
    if not creature:isMonster() then
        return primaryDamage, primaryType, secondaryDamage, secondaryType
    end

        if attacker and attacker:isPlayer() then
            if primaryDamage > 0 then
                            print(creature:addHealth(-hp))
            end
            if secondaryDamage > 0 then
                print(creature:addHealth(-hp))
                   end
        end
    end
    return primaryDamage, primaryType, secondaryDamage, secondaryType
end

in this other script I'm trying to make sure that whenever he hits and globalstorage is active he suffers a random attack

First script you should check if t exists before doing t:getItemByID.
You can either add to the preexisting one or just add another if statement above to check if t exists.

 function onHealthChange(creature, attacker, primaryDamage, primaryType, secondaryDamage, secondaryType, origin)

    if not creature:isMonster() then
        return primaryDamage, primaryType, secondaryDamage, secondaryType
    end
    if getGlobalStorageValue(91231522) >= 1  and creature:getName() == "demon"  then 
        if primaryType == COMBAT_HEALING or secondaryType == COMBAT_HEALING then
            return primaryDamage, primaryType, secondaryDamage, secondaryType
        end    
        if attacker and attacker:isPlayer() then
            if primaryDamage > 0 then
            local hp = math.random(2000,7500)
            creature:addHealth(-hp)
            end
             
            if secondaryDamage > 0 then
            local hp = math.random(2000,7500)
            creature:addHealth(-hp)
            end
        end
    end
    return primaryDamage, primaryType, secondaryDamage, secondaryType
end

this one works but the char that attacks it needs is close to the monster if I was far away it doesn't work
