My script to get the color and material not working, what is wrong???

So, I made a script to get a two values, then make a part using those. I have a StringValue called current, which would keep a value like "Brick" and a Color3Value called CurrentColor which would contain an RGB value, like "248, 0, 9" and when I try to reference them in a script to make a block out of them, it errors. My script is:

local rs = game.ReplicatedStorage
local event = rs.GrassPlace
local current = workspace.Current
local color = workspace.CurrentColor

function place(plr,target,blocktype)
    local newBlock = Instance.new("Part")
    newBlock.Size = Vector3.new(4,4,4)
    newBlock.Anchored = true
    newBlock.Material = current
    newBlock.BrickColor = color.Value
    newBlock.Name = current.Value
    newBlock.CFrame = CFrame.new(target.Position) + CFrame.new(0,4,0)
    newBlock.Parent = workspace
end

event.OnServerEvent:Connect(place)

I also have a script inside a GUI that changes the "Current" value. If it helps, that script is:

local current = workspace.Current
local colorValue = workspace.CurrentColor

script.Parent.MouseButton1Click:Connect(function()
	current.Value = "Brick"
	colorValue.Value = script.Color.Value
end)

Please help me!!!

First, if you want to use a variable as a key for any table, you use table[variable], or Enum.Material[current] in this case.

Second, to make a BrickColor from a Color3 value, you can do BrickColor.new(color) or insert the RGB values separately BrickColor.new(color.r, color.g, color.b)

Fixed code:

local rs = game.ReplicatedStorage
local event = rs.GrassPlace
local current = workspace.Current.Value
local color = workspace.CurrentColor.Value

function place(plr,target,blocktype)
    local newBlock = Instance.new("Part", workspace)
    newBlock.Size = Vector3.new(4,4,4)
    newBlock.Anchored = true
    newBlock.Material = Enum.Material[current]
    newBlock.BrickColor = BrickColor.new(color)
    newBlock.Name = current
    newBlock.CFrame = CFrame.new(target.Position) + Vector3.new(0,4,0)
end

event.OnServerEvent:Connect(place)

The reason it because your doing BrickColor.color() not color.Value Your also adding a Vector3 to a CFrame; fixed that too

local rs = game.ReplicatedStorage
local event = rs.GrassPlace
local current = workspace.Current
local color = workspace.CurrentColor

function place(plr,target,blocktype)
	local newBlock = Instance.new("Part")
	newBlock.Size = Vector3.new(4,4,4)
	newBlock.Anchored = true
	newBlock.Material = current.Value
	newBlock.Color3= color.Value
	newBlock.Name = current.Value
	newBlock.CFrame = CFrame.new(target.Position) + CFrame.new(0,4,0)
	newBlock.Parent = workspace
end

event.OnServerEvent:Connect(place)
