Move Cube from Array with timeline

[lecinema]

Hi everyone,
I made a grid of cubes, now I want to move some cubes randomly with timeline.
I can change the x coord of cubes randomly.
But not with timeline.
I don’t understand why.
Every help is welcome.
Thank’s

If they are cube BPs, you can just put the timeline in the BP. Then choose one randomly, and tell it to move

Thank’s for the answer
effectively, I must be tired yesterday
If I call the function CubeMove (who’s inside the BP_Cube, with a timeline to move on x), from the Level BP, it works.
Thank’s a lot !
