Propagate TextBox value to dedicated server and print it to server log

Hi All, I started playing with UE4 and especially around usage of dedicated server, so far I was able to achieve the following:

  1. I have a default game level, that
    does nothing but runs “open :”
    console command on BeginPlay

  2. Once connected server pushes second level
    to client which presents a UI widget
    with a couple of text boxes and
    submit button

Now this is where I am stuck, I have an OnClicked event for the button, that leads to Set for variables corresponding to text boxes values, and I’ve setup OnRep_ functions to “Print string” to both screen and log - I can see Print happening on Client, but not on the server.

Am I doing it completely wrong or am I missing something?
