Quick question about ADC in a PIC18F04Q41

I am either experiencing a senior moment or I never understood how channel switching for the AD converter works.

Before I elaborate on what the problem is, can I ask: do you need to issue a
Code:
set_adc_channel(sAN2);
before every read of an ADC value? Also if I am only interested in on input channel?

Yep, senior moment.

Reading my own question back I noticed the 'sAN2' and thought, that cannot be right....
And indeed, changing this to
Code:
set_adc_channel(2);
solved my problem.

My excuses for the stupid question.
