The result of a multiplication is not automatically updated in the app

[Jujuy_Adventure]

Hi!
I have encountered a problem that I cannot understand.
I have created a tableX where I collect information from tableY and tableZ.
When I want to do a multiplication of these two data in my tableX, it only computes the data when, by default, it receives all the data.
If I want to change any of the multiplication variables, it does not update the result.

in this first case I have provided the data by default using"Initial value".
As can be seen, the parameters that are multiplied are “USD X Pax” * “Precio 3” and the result is correct.
but if I decide to change any of the parameters on which these values ​​are dependent, the result remains unchanged

Does anyone know how I should make the result update instantly?
Thanks
