* Help with source template expression

[Peter Collier]

I have a date field in a source template called "Publication date". I want to be able to separate the day and month from that field to suit a particular footnote style.

{Publication_date:YEAR} separates out the year for me, and I can get half way there with the day and month by using the expression {=Day(%SOUR.~DT-Publication_date%)} {=Month(%SOUR.~DT-Publication_date%)}. However, {=Month... returns the month number, whereas I want the (full) month name.

I know that is the correct behaviour for =Month. How might I change the expression, so that I get the full month name, rather than just the month number?

In full, the footnote format currently reads:
<{Author}.> <({Publication_date:YEAR})> <'{Article_title}'.> <i>{Publication_title}.</i> < {=Day(%SOUR.~DT-Publication_date%)} {=Month(%SOUR.~DT-Publication_date%)}.> <{Page_and_column}.>

The output, as I want it to appear, would be (for example):
Higginbottom, Josiah. (1880) 'Stealng a Loaf'. Derby Daily Telegraph and Reporter. 12 March. p. 3

Currently, I am getting:
Higginbottom, Josiah. (1880) 'Stealng a Loaf'. Derby Daily Telegraph and Reporter. 12 3. p. 3

Instead of using FH Functions, use Date Qualifiers like you are with :YEAR as defined in the Help page Date Formats.
i.e.
{Publication_date:DAY} {Publication_date:MONTH_NAME}

Unfortunately, that doesn't work. I get the following error message:

That is what pushed me down the function route.

I should add, the same error message appears, mutatis mutandis, for the title, bibliography, and short footnote. The error doesn't just appear for the footnote format.

Sorry, I'd overlooked that only the :YEAR Qualifier works on Date Field {Name} (for some reason that only CP can explain).
So you must use the Data Reference alternative which does work:
{%SOUR.~DT-Publication_date:DAY%} {%SOUR.~DT-Publication_date:MONTH_NAME%}
which makes explaining why {Publication_date:DAY} {Publication_date:MONTH_NAME} don't work even stranger.
Perhaps you'd like to ask CP
