Spawned Mobs Do No Damage? Help/fix?

[GlacialDew]

So I coded a few custom bosses but they dont actually do any damage. Is there a fix or way to make them cause damage like a collide event?

    if event-block is not air:
        if player is holding a enchanted book with name "&8&lSpider Queen Summoner" with lore "||&7Summons A Spooky &2&nSpider Queen":
            send "&7[&6&lAA&7]&7 The &2&lSpider Queen Boss &7Has Been Summoned!"
            spawn 1 spider 1 above event-block
            set the name of the last spawned spider to "&2&lSpider Queen"
            apply resistance 2 to the last spawned spider for 9999 minutes
            push the player backwards
