Okay, so assuming you want "Series Name [03] Book Title" as per post #533.

series_index should be prepended with underscores, to bump it up to 4 digits.

If the custom column "#complex_series" is set to true -- I'll just test if it has any value -- it will add two decimal places. Mark each awkward series with this.
(This would be easier if I could figure out how to test within a template for a numer with decimals.)

Template should be:

program:

ser_num = test(
	field('#complex_series'),
	finish_formatting(
		field('series_index'),
		'_>7.2f',
		' [',
		'] '
	),
	finish_formatting(
		field('series_index'),
		'_>4d',
		' [',
		'] '
	),
);

strcat(
	field('series'),
	ser_num,
	field('title')
)

(You can delete whitespace if you want, but I left it in to clarify what I am doing.)
