Button Replication

Good Day,

I tried to replicate my button, but it doesnt work in multiplayer.
If I play with one player the blueprint works excellent, but if I have a server and a client my blueprint doesnt work for everyone. On the screen you can see my standard call for the event. The event calls my progress, but first a string with a text. The text is only show in singleplayer not on multiplayer. That means that if I press the button it doesnt send it over the event. Not with server and not with client.

Does somebody know how to fix this that I can press the button and the server, client or both see the event?

I hope somebody can help me. If you have a question just ask.

Sincerely
