script is not working in multiplayer mode ???

Hi thank you for reading this I appreciate your help any help because i am stuck in something every player has a game tag and if that game tag is true that player can mine but if it'S false they will not be able to mine here is the code for setting the game tag

this code is in the serverscriptservise.

view source

	for i,players in pairs(plrs) do
	        local character=players.Character or players.CharacterAdded:Wait()
	        if character then
	 
	            builder.Value=true
	            builder.Parent=character
	            print("i am allowed")
	        else
	 
	            if not players then
	                builder.Value=true
	                builder.Parent=character   
	                table.remove(plrs,i)
	                print("removed")
	            end
	 
	        end
end

and here the script I check on if they builder tag is true i serverscript is in the map that the player mines in al players get teleporter to their mining surface and in that surface i check this.

view source

	if (builder and builder.Value)then
	     --code
	end

and this works fine when I play this alone but when i test this with 3 players then only 1 player can mine and all others can not please if u know how to solve my problem then answer it thank u for taking the time reading.
