I am hoping that someone can help me figure this out. Based upon the information that I am reading in the manual and documentation it
should be doable, but I may be missing something.
I have three Custom Columns that are the following:
- chapters - Integer
- last_chapter_read - Integer
- chapters_remaining - Composite
What I am trying to do is have the chapters_remaining column calculate the difference between chapters and last_chapter_read. There is a math function called subtract (x, y) that by all appearances should do the job that I want to do. Unfortunately all attempts I have made at getting this to work have failed with differing errors depending upon what I have entered for the template.
Can someone help me figure this out?
