How to change a Text Box once the player has fully respawned?

I'm making a script where the player uses keybinds and what not to activate certain moves. I've done the whole part of making where the player uses the move to what ever button he presses, but I can't figure out a way for that same letter to stay in the button after the player dies. And the gui automatically detects the letter even if the player died or not. This is my attempt. Thanks for your help!

Server Script

game.Players.PlayerAdded:Connect(function(Player)
    local char = Player.Character or Player.CharacterAdded:Wait()
    local hum = char:WaitForChild("Humanoid")
    hum.Died:Connect(function()
        local DiedAttack = Player.PlayerGui.DiceShopGui.ScrollingFrame.Frame:WaitForChild("AttackBoostFrame")
        print("Player has died")
        Player.CharacterAdded:Wait()
        local PlayerGui = Player.PlayerGui
        print("Player has respawned")
        PlayerGui.DiceShopGui.ScrollingFrame.Frame.AttackBoostFrame.ProductImage.ProductTextBox.Text = "G"  
    end)

end)
