'Max' of text field doesn't work in related records?
The manual for the 'max' function states 1. it works for text fields, and 2. it works over related records.
However from my testing I've found 'max' works for text fields within the same record, it works for numeric fields in related records, but not text fields in related records.
This would be consistent with the 'max' summary field which also can't process text fields.
Sounds like the manual needs updating?
