Having a bit of an issue with my location names...

My game features areas where different length races are taking place (100 metres, 400 metres etc.)  These area locations are named 100_metres and so on...

100_metres : location ;
400_metres : location ;

...but the title bar doesn't display the number at the start of the location title and just says 'metres'.

Any advice, or am I just going to have to reword these somehow?

Not at computer at the moment but try putting the name in quotes after the location.

I think that I added special numeric prefix stripping from the header (for use in gamebook mode).

Anyway, try this:

100_metres :location "100 metres";

That worked - thanks!
