Question: Is undefined the same as '0' in a days_between?
Code:
program:
read = $$#lastread;
updated = $$#fanficupdated;
if $$#percentread <# 100 && days_between (read, updated) <=# 0 then '#ffff7f' fi
This activates on books that have an undefined #fanficupdated, though if I change it to
<#0 that fixes it.
