You should update your manuals... It´s super difficult for a a beginner to follow "step-by-step" instructions, when in fact, either there are steps missing, or there are steps not updated, or there are steps that don´t even make sense with little to none explanation. E.g. "create a new Screen Action", when there´s only "new Screen" or "new Client Action"... (It´s new client action fyi)
