Why Does A For Loop Return "attempt to get length of a Vector3 value" - for-loop

Question

I have no clue what is wrong with this code, it is literally saying that a for loop that is perfectly fine, is attempting to get a vector3 value.
local locations = {}
local Players = game:GetService("Players")
local function SplitString(String)
local CurrentString = ""
local x = 1
for i = 1, #String do
local FullString = string.sub(String,1,i)
local Character = string.sub(String,i,i)
local CurrentString = string.sub(String, x, i)
print(locations[1])
if Character == "," then
CurrentString = string.sub(String,x,i-1)
table.insert(locations,CurrentString)
x = i + 1
CurrentString = string.sub(String, x , i)
print(locations)
end
--Add the character to the string.
if Character == " " then
x = i + 1
CurrentString = string.sub(String, x, i + 1)
end
if #FullString + 1 == #String then
table.insert(locations, CurrentString)
end
end
end
Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(char)
local humanoidrootpart = char:WaitForChild("HumanoidRootPart")
wait(5)
while humanoidrootpart do
local location = humanoidrootpart.position
print(location)
SplitString(location)
print(locations[1])
local RoundLocatX = math.floor(locations[1]*50)/50
local RoundLocatZ = math.floor(locations[3]*50)/50
local RoundLocatXLength = RoundLocatX.length
local RoundLocatZLength = RoundLocatZ.length
if RoundLocatX > 50 then
print('hi')
end
wait(1)
end
end)
end)
This is the error:
ServerScriptService.Terrain Generation:9: attempt to get length of a Vector3 value
I would post this on the roblox forum but they are stupid and require some dumb amount of reading time to be able to post on it.

Your error is pointing at this line :
for i = 1, #String do
and saying that you are trying to get the length of a Vector3 object. That means that #String is not working as expected. So looking at the object you passed into the SplitString function...
local location = humanoidrootpart.position
print(location)
SplitString(location)
Your location variable is a Vector3, not a string, and it doesn't support the length operator, #.
But you don't have to parse it as a string to get the values out of it. Since it is a Vector3, you can simply index the different values in it.
local location = humanoidrootpart.Position
local RoundLocatX = math.floor(location.X * 50) / 50
local RoundLocatZ = math.floor(location.Z * 50) / 50
