How the heck an I supposed to make this local script work?

local player = game.Players.LocalPlayer

--all of this goes in a local script, which is in a part

script.Parent.Touched:connect(function(toucher)
if game.Players:FindFirstChild(toucher.Parent.Name) then	
	wait(0.5)
local a = math.random(1,25) --set the 100 to whatever number you want. setting it higher lowers the chance of getting pulled into a wild battle.
local b = math.random(1,1)--set the 1 on the right in the parenthesis to however many pokemon you would like to be in the grass.
print(a)
if a == 1 then

print("A Wild Pokemon Appeared!")--Not necessary, just shows that the script is working in the output. Remove this line if you want to.
	
	
if b == 1 then

--If you want more than one pkemon to appear in the grass, then copy and paste the entire "if b ==1 then" statement and paste it under it and also change the value of b, which is all the way back at the top.
--Example of adding more pokemon:
---------------------------------
--if b == 2 then
--asset = ______
--model = game:GetService("InsertService"):LoadAsset(asset)
--model.Parent = game.workspace
--model:MakeJoints()
--model.Name = "MySecondPokemon"
--model.MoveTo(game.workspace.Grass.position)
--print(Hey, It's a MySecondPokemon!")
---------------------------------
end
end
end

I've been modifying this script non-stop for 4 hours. I just figured out that the hecking thing doesn't work in game. It says things like 'Attempt to index LocalPlayer' or sometimes it doesn't work at all. Help please. ;-;
