I need help with a player avatar gui image???

My error is at line 10 and 9. I am trying to show the player avatar on a gui shown to all players. My error in the output is "Nil" and I believe it is the print function. but it is caused by line 10

local pic = script.Parent

local player1 = game.ReplicatedStorage.heist1Values.Player1.PlayerName
print(player1.Value)

while wait(0.1) do

    if player1.Value ~= "none" then
        local player = game.Players:GetChildren(player1.Value)
        print(player.DisplayName)
    --local player = game.Players.LocalPlayer

if player.Name == player1.Value then

local userId = player.UserId

local thumbType = Enum.ThumbnailType.AvatarBust

local thumbSize = Enum.ThumbnailSize.Size420x420

local content, isReady = game.Players:GetUserThumbnailAsync(userId, thumbType, thumbSize)





            pic.Image = content
            end
    end
end
