Moving Multiple Static Meshes Along Spline

I am trying to write a blueprint that allows me to move multiple objects along a spline. For example, cars driving along a spline. In my current blueprint I am able to get one car to move along the path, but I am having trouble when introducing a variable that allows me toggle the amount of cars along a spline. Anyone have any thoughts here. I attached a screenshot of my current BP here.

Hey there, did you ever manage to solve this? I am facing the exact same issue.
