I'm just trying out Cataloguing for the first time with custom columns and so don't have much info - for now.

I've created a column and used the text etc. for column type. I want to change this to a yes/no type but Calibre will not allow editing here - what might I have done wrong.

Also, if I understand correctly if I tick-off the check mark the answer should show a green check mark or red cross - this doesn't seem to work for me.

Any help?
Thanks
