Help with math.random?
Every time I try to run this script I get a error saying:
Workspace.Script:16: bad argument #2 to 'random' (number expected, got nil)
Here is the output:

This script is suppose to spawn a part in a random spot using the baseplate's position--]]

Part = Instance.new("Part",game.workspace)
RPosition = SpawnRandomPostion(BaseplatePositions[1],BaseplatePositions[2],BaseplatePositions[3])
Part.Position = RPosition
Part.Anchored = true
print(RPosition)--Check
Why did I get this error and how do I fix it?
If you manged to fix it show me how you did it,thank you.

The problem, as it says, is that the "second argument to math.random is nil".
That means X is nil. X was the first argument passed to SpawnRandomPosition, so that must mean that BaseplatePositions[1] is nil.
If you check that (print it out) you will in fact see that it's nil. Why?
Because the BaseplatePositions has three things in it, but none of them are at 1, 2 and 3 -- they are at "BaseplateX", "BaseplateY", and "BaseplateZ".
Thus you could fix this like this:
RPosition =
SpawnRandomPostion(
BaseplatePositions.BaseplateX,
BaseplatePositions.BaseplateY,
BaseplatePositions.BaseplateZ)
OR you could fix this by changing the definition of BaseplatePositions to not have the BaseplateX =, etc.
You will encounter a very similar problem on line 22.
