Little bug in Raymond Fain's edited socket

programming
1

Hi
I’ve edited Raymond Fain’s socket server to have a multidimensional array of online users.
It works fine, but when i close client windows i face to a warning about socket_select in line 72.
Anybody knows where is the problem?
Thankyou
Here is the code and files have been attached.
