Hi, I don't know what to do with one of my chains. The end of the chain is supposed to count the ebook's pages using the 'Count Pages' plugin using the Goodreads metadata. Everything is fine. The problem is that sometimes Goodreads doesn't have the page count in its metadata, which leaves me with a blank space in the corresponding column.
I have to enter the value manually or press 'Estimate page/word count' in the 'Count Pages' plugin. I added it to the chain and added the condition that it would run if the column was empty, but it doesn't work.
I don't know what to do.
