assign excel cell material density

[LucaRF]

good morning to all, I have a parametrised model of a structure (managed by excel cells through analysis) on which will be mounted pieces of which I do not have the model but I know the weight and position of their centerpiece compared to the structure.
to calculate an approximate centerpiece of the complete model I mounted a small cylinder of volume known and modified by hand its density to have the desired weight for the calculation of the centerpiece.
my question is whether it is possible to assign the density of the piece in the relationship by parameter (this would prevent me from having to change the density by hand whenever the weight of the pieces to be mounted on it changes).
thank you very much to all in advance for the answers.

Good morning, you need to check if you can value mp_density with a relationship that takes the value of a parameter created ad hoc and valued by excel analysis

thank you so much I tried and it works
