MIDI Control of Cine Camera Focus

I made a BP based on Aiden Wilsons YT Video to get my MIDI Controller to work in UE, which works fine.
Now, after two faders work for Sun Positioning, i want to control the Camera Focus with the next Fader, but it wont work with teh BO i created.

In the Event Graph i mapped the Fader 3 to a “Set Focus” function with a float input called “Fader Value” i created.
Here is the Graph i made, but i doesnt work, and i have no clue where the bug is, anyone a suggestion ?

Quite new to blurprints and Unreal in general, but love every day, but sooo muhc to learn :slight_smile:
