Thanks for the information, tech.

Here is a short pointer to some key features (one minute long)

The Cloner.driver can be set to any number of clones. It always produces the top end Pos.Y information of the bars. The other cloner is always on the bottom.
Each bar can be animated with a Cube-Field. I have two of them inside. Or just by the Random effector.
There is a “Kill_TP_Pos.Y” null object. The Y position of this object will kill all the particles above that Y value. Animate the Null, if needed.
The Dollar signs are in an extra Cloner, and their positions are TP based.
I hope that is a little bit simpler than the file before.
Add the Effectors that you need accordingly.
Enjoy
