Why do my if statements both pass, no matter what I do?

        table.insert(NPCs, descendant)
        descendant.Head.InteractGui.Interact.Size = UDim2.new(0, 0, 0, 0)
    end
end

            closestNPC = NPCInRange
        end
    end

end)

    end

An NPC needs a option1, option2, and and dialogue. Whenever I go to a NPC, it works fine, but the moment I go to another, it gives both of their things at the same time. I really don't know what the problem is. Please help? Thank you!
