Add the highlighted nodes shown in the below images, you will need to create a float input on the function

Next you will need to add the float value to the event

For the next nodes you need to add the easiest way would be to right click the Client Updates Storage event and select Find References, that will return all the places the node is used, you will then need to get the max weight float from the storage component variable and connect it to the event.

Below are screenshots of all the places but as i say above its much quicker to right click the Client Updates Storage event and select Find References, that will return all the places the node is used and click through them.
