Test book with only a PAPERLOAN format, returns eBooks. What I do wrong?

EDIT: ('OVERDRIVE' inlist_field 'formats' || 'PAPERLOAN' inlist_field 'formats') works, was hoping to avoid repeated.

inlist and inlist_field have a regular expression on the left hand side. You put a boolean expression. What you want is a regular expression using alternatives.

This should work:

program:

bookformat =
	switch_if(
		'PAPERBOOK' inlist_field 'formats', 'Physical Books',
		'OVERDRIVE|PAPERLOAN' inlist_field 'formats', 'Loans',
		'eBooks');
