Hello! I bought a professional edition and for 3 days I've been trying to understand how it works. When writing such code and clicking on 'T', as a result, messages from the client do not come and the ip server is always equal to "nil". Please help me. Sorry in advance for maybe a stupid question.  Output: msg = absent; bb = nil; cnt(if enable) = 1;
