Dynamic Parameters

Hi everyone, 

I have a question if anyone can help I would appreciate and thanks in advance.

I have 2 data sets which I can not connect.

First one has the tenant names with the profit margin for every each tenant. 

2nd has the zone names with the average prices for every each zone. 

Also every tenant is in a specific zone. 

What I am trying to achieve is : When a tenant log into their account with their zone, I am trying to pass their margin to the other dataset, so that their margin adds up to the average prices and every tenant can see their sum price (average+margin). 

Is the solution with using the dynamic parameters ? I tried and couldn't figure it out. 

Thank you.
