Capture data through a button to send to a dashboard

Dashboard
,
1

Hello everyone
I'm trying to load data in a "form" when the buttons are clicked.
Simulate sending data through a serial node using a random number generator.
Practically I needed that at the moment of selecting the left button, take the generated data and place it in the "Left Weight" box.
I would appreciate your help please
Thank you
Next I leave a screenshot of my flow and the code that I am doing.

In my code the "Peso Izquierdo" and "Peso Derecho" fields are entered automatically, but I need them to be entered only when I click the "Izquierdo" and "Derecho" button of the "Actualizar" group.

Again not fully understanding, if this is not going in right direction i will need a fully explanation, maybe with diagrams.

Ok, but I want the "set msg.payload" node to be before the button nodes.

As shown in the picture

Then blend the 2 examples to pass the payload through the button nodes.
e.g.

Sorry to keep bothering you, I need to do the same process as the previous answer.
In the code I want the load sent by the node inject to pass only when the button node allows it.

Beforehand thank you very much

I already showed you how to pass a payload through a button node, you will have to apply it to your flow.

Here is another example of how to pass a payload through a button node, using a join and a switch node. I include the first example to.
