For digital potentiometers which ports must be unique to each potentiometer and have their own respective digital ports on the Arduino.
Clock and data can be shared, but CS (chip select) most use it's own pin.
What are you trying to do.
Beginners often think a digital pot is the answer to their problems, but then realise that the pot signals need to be within the limits of the supply/ground of the pot chip.

thanks very much
I've already tested my setup with a single pot so i believe i'm good
Post your sketch.

So what are you doing? Typically the only need for a digital pot is with analog audio volume control,
usually a DAC is the answer for other cases, not a digipot.
