Argument 1 missing or nil?

I'm writing a sword script. When someone clicks, A random selection (of 3) is ticked. This plays an animation via the Animation Script. I get this error:

19:21:14.931 - Argument 1 missing or nil 19:21:14.931 - Script 'Players.Player.Backpack.Wooden Sword.SwordScript', Line 155 19:21:14.932 - Stack End

and I have no idea why. I have never come across this error before. This is the part of the script that errors.

function onActivated() 

    if not Tool.Enabled then return end 

    Tool.Enabled = false 

    local character = Tool.Parent; 
    local humanoid = character.Humanoid 

    if humanoid == nil then return end 

    attack() 

    local num = 5 --Change 5 to the number of maps you have
local anims = {"PlayThrust", "PlaySlash", "PlayOverhead"} --Put their names here, add more if you have to


local m = math.random(1,num)
script.Parent:findFirstChild(anims[m]).Value = true --error here





    wait(1) 

    Tool.Enabled = true 
end

Any help is appreciated. Thanks!

You have a table called anims that holds 3 values and a variable called num with the value 5

You are calling a random number between 1 and num or 5 when there are only 3 values in the anims table.

    local num = 5 --Value is 5
local anims = {"PlayThrust", "PlaySlash", "PlayOverhead"} --Only 3 indexes


local m = math.random(1,num)  --Random number between 1-5
script.Parent:findFirstChild(anims[m]).Value = true  --If the random number is greater than 3, it will be nil

If the math.random returns something greater than 3 it will be nil and give an error.

Let me know if that is your issue, if not I will look into it further!
