@scottvonduhn the line it references has nothing to do with a break and all the breaks have self-terminating tags

Yes, I saw that you did say there is no break on that line, but you provided no code or context regarding the issue. Quote PDF could be anything. I have an Invoice PDF that does not reference any invoice or transaction fields, because it is used for a special purpose. Which is why I said that without seeing the template code, it’s hard to say what the problem is, so I could only speculate about the problem. Is this error happening when trying to save changes to the template, or at runtime (generating the HTML or PDF document)? Other possibilities are that there is an implicit line break being inserted. Text fields with a new line / line break will have the line break converted to a br tag when substituted into the template, but that happens at run-time, not when saving the template.

Line numbers in BFO errors will generally not relate to the template code because they are working on the code after Freemarker has merged the template with the record.
