(Noob here)(Simple Script) Need help with a Vector3 Function?

script.Parent.Touched:Connect(DoDOMove() should be script.Parent.Touched:Connect(DoDOMove). The Connect function takes in a function that is called whenever the signal is fired, however you're providing a function call. And you're missing parenthesis.

Lowercase Workspace. It's deprecated.

I'd also advise removing the backticks from the end of line 3.

Also, are you aware that math.random is a function, not an object / property? Call it by doing math.random(). If you want it to return an integer from x to y, then do math.random(x,y); x and y being the min and max value, since math.random() by itself returns a non-integer value (range [0, 1])

So there are some issues on your code, ill list them

.1 Line 6 is incorrect, it has to be like this

script.Parent.Touched:Connect(DoDOMove)

-

.2 math.random doesnt work like that, you have to give it a min and a max number like this:

print(math.random(1, 5)) --will print a pseudorandom number from 1 to 5

-

.3 Theres no reason to do this in your case

script.Parent.Position = Workspace.DoDO.Position +

You should just do this

script.Parent.Position = yourValues --this is just an example.

-

.4 Vector3 has three axes, X Y and Z. You are setting it to math.random so it wont work.

You have to create a random number for each axis, so you could do something like this

script.Parent.Position = Vector3.new(math.random(1, 5), math.random(2, 5), math.random(5, 10)) 

--[[
EXPLANATION

X = math.random(1, 5) == pseudorandom number between 1 and 5
Y = math.random(2, 5) == pseudorandom number between 2 and 5
Z = math.random(5, 10) == pseudorandom number between 5 and 10 
]]

.5 Not an error just an observation, you should probably add a debounce to that script
