how does one add an internal link?

I have chapter 'Framework' (and file 'Framework/Framework.pillar') and 'Palette' (and file 'Palette/Palette.pillar')

Can I in Framework.pillar write something like *Palette/Palette* to create a link?

Currently it fails at

*** Warning: PRReferenceNotFound: Can't find anchor named 'Palette/Palette'

Thanks,

Peter
