String expected but I already gave a string?

So I made a function that makes several Guis for me and and I got a error saying:

String expected

Script 'Workspace.Script', Line 22 - global CreateButton

Script 'Workspace.Script', Line 30

Why did I get this error if I'm giving a string by using the symbols ""?

How do I fix this error?

function CreateButton(Size,Position,ButtonSize,ButtonPosition,PlayerImage,Parent)
----------------------ObjectTable----------------------
local Objects = {}
----------------------Button----------------------
local Button = Instance.new("TextButton",Parent)
Button.Style = Enum.ButtonStyle.RobloxRoundButton
Button.Size = UDim2.new(ButtonSize)
Button.Text = "PlayerName"
Button.Name = "Button"
Button.Position = UDim2.new(ButtonPosition)
table.insert(Objects,Button)
----------------------ButtonUnderImage----------------------
local Buttonunderimage = Instance.new("Frame",Parent)
Buttonunderimage.Style = Enum.FrameStyle.DropShadow
Buttonunderimage.Size = UDim2.new(Size)
Buttonunderimage.Name = "ButtonUnderImage"
Buttonunderimage.Position = UDim2.new(Position)
table.insert(Objects,Buttonunderimage)
----------------------PlayerImage----------------------
local PlayerImage = Instance.new("ImageLabel",Parent)
PlayerImage.BackgroundTransparency = 1
PlayerImage.Image = PlayerImage
PlayerImage.Name = "PlayerImage"
PlayerImage.Position = UDim2.new(Position)
PlayerImage.Size = UDim2.new(Size)
table.insert(Objects,PlayerImage)
----------------------Returninig----------------------
return(Objects)
end
Button = CreateButton(
