[Koha] Fields B_address and B_address2 of Patrons' File Does Not Display Content when I Create Patron Card

Hello All, I have put <B_address> <B_Address2> in the text box of one of the fields in "Edit Layout" Window. When I opened the resulting PDF file generated from managing batches, exact texts in the field's text box were returned just as they were input instead of displaying the values in the fields. However, when I input <address> in the textbox of the same field, and I ran the Batch export, it display the correct values. What could be wrong with the fields <B_address> and <B_Address2>. Any help about this please? Your advice will be appreciated. Thank you. Olufunmilayo FATI University of Jos Library Nigeria
