game.Players.LocalPlayer can only be accessed from a LocalScript. It's nil inside of a Script.

"Touched" is an event not a function.

Is this a local script

Next time use the code block feature. It's the Lua Button

##Problem

Seeing as your code is located in Workspace, I am assuming this is a server script. In which case, ServerScripts can not access LocalPlayer. This is one of the more common mistakes I have cited in my blog article.

##Solution

There are two ways of going about this.

Using a LocalScript

You can rename the part in Workspace to something unique. Whenever the character hits the part then the GUI elements can change. This is actually recommended as you're dealing with GUI elements which should be handled by the clients. This method is also compatible with FilteringEnabled environments.

Using a ServerScript

You can keep the script in the normal location and gather the player from the GetPlayerFromCharacter method. Once gathering the player you can go into the PlayerGui and modify the text.

##Final Script

####Solution 1 (LocalScript Method):

LocalScripts will only work in PlayerGui, a Player's Backpack, PlayerScripts, or the Player's Character.

game.Workspace.PartNameHere.Touched:Connect(function(partThatTouched) --Fire a function every time the Touched event fires. partThatTouched is the part that touched the brick.
    if partThatTouched.Parent == game.Players.LocalPlayer.Character then --Make sure it is the character hitting the brick and not some other brick.
        game.Players.LocalPlayer.PlayerGui.PlaceGui.MainFrame.TextShower.Text = "Testing" --Change the text. You can decide how the vairables are set.
    end
end)

####Solution 2 (ServerScript Method):

script.Parent.Touched:Connect(function(partThatHit)
    local player = game.Players:GetPlayerFromCharacter(partThatHit.Parent) --Function will return the player object. This is gathered from the character from the parent of the partThatHit.
    if player then --Check to see if the player exists or if some random brick hit the part.
        player.PlayerGui.PlaceGui.MainFrame.TextShower.Text = "Testing" --Change the text.
    end
end)
