I was trying to make it show Goodreads only if the ISBN didn't exist. It didn't quite work as expected.

I'm still trying to figure these out.

There are several errors in this template.

• You need semicolons between the statements.
• There is no function identifier_in_field. I think you mean identifier_in_list, but regardless you don't want to use it. Instead use 'select'.
• You are missing a second fi (as Terisa de morgan said

That said, if I understand what you want to do then this template is does the job.

program:
	i = field('identifiers');
	ifempty(select(i, 'isbn'), select(i, 'goodreads'))

If you really want to use an if statement then this works.

program:
	i = field('identifiers');
	p = select(i, 'isbn');
	if p then p else select(i, 'goodreads') fi
