switch: CE6810

I can't get a stack to establish, when I do "dispay stack troubleshooting"  I get this error:

Configuration conflict: The Stack-Port of the member port on the local device is different from that on the master device.

Does it matter which stack Interface connectes between switches?

e.g do I need to have stack interface 1/2 to connect to 2/2?

or do does it need to be stack interface 1/2 connect to 2/1?

or does it not matter?
