How to get different measures in report

Hi dears, I'm new both on PBI modeling and this great community!

I'm in charge to develop a new report showing the inventory level both in pcs and value but only one value at time.

I've the following table:

PRODUCT     WAREHOUSE      QTY      VAL
Bike               Canada                500     5000$

Cars               USA                       50   12000$

and so on.

How can get a report showing alternatively QTY and VAL?

I've tried to use the PARAMETER by selecting FIELDS instead of MEASURES but I only retrieve the LABEL (QTY/VAL) instead of the current measure.

Could you kindly explain me what is the best way to manage this issue? Have you any link "graphical" to show me the way since I'm a newbie?

Thanks in advance
