Reply To: empty field in database not handled as expected

It works in all my testing. Make sure you don’t have a local copy of the function in your invoice plugins directory. I removed them all from the standard version and have worked with this in testing the logic in the various templates and it works fine. I’m in the middle of making some significant changes to SI which includes enhancements to these functions to using multiple labels values and such. So it will be a little while before I get those delivered.
