Hi @JHulet
what's the text mode you're using for "Predecessor project percent complete"?
In general - the number of hops might be an issue with something like {predecessor}.{project}.{owner}.{name} because you want to display the name not just ownerID (a property on the project)
You could try setting a calculated field on the task, and display the field in the report.
Let me know how it goes!
