Character won't load animation?

I don't know much about making animations, but I know how to play them (i think). Whenever I try to load the animation, it does nothing. Output doesn't say it didn't load, and sometimes when i walk or jump the animation plays but it didn't play in the moment. Help? This is the script, broken down to the more important parts. (its a vent for an among us copy by the way, making the player jump in felt lazy)

animEnter = p.Parent.ventEnter
local c = plr.Character
local h = c.Humanoid
local ventplay = h:LoadAnimation(animEnter)
-- variables
p.ClickDetector.MouseClick:Connect(function(plr)
	if plr.Character.Torso.Transparency == 0 and plr.IsTraitor.Value == true then
	ventplay:Play()
	end
end)
--code

There's a lot more to the script, but I broke it down to what I need. Everything is good, traitor value is true, torso is opaque. I just don't understand, did I code wrong or is it my crappy PC?

It seems like the problem is that the character hasn't load yet, therefore the animation can't load. Since animations play through a local script, you should define the local player.

animEnter = p.Parent.ventEnter
local player = game.Players.LocalPlayer
local character = player.Character or player.PlayerAdded:Wait() --Define character
local humanoid = character.Humanoid
local ventplay = humanoid:LoadAnimation(animEnter)
-- variables
p.ClickDetector.MouseClick:Connect(function(plr)
    if plr.Character.Torso.Transparency == 0 and plr.IsTraitor.Value == true then
    ventplay:Play()
    end
end)
--code
