add button not working

[stre_l0k]

Hello, I am using a LAN plugin and mx player. When playing each file individually, everything works well, but if when I created a button with such parameters, when I open the player it gives an error saying that it cannot play this file, tell me what is my mistake?

That's because you try to pass a name to mxplayer which isn't a local file.
