Portal problem - portal shows one less than records in table
I have a simple Portal for my "Items" table which has the traditional relationship of Items>---not equal---<Items2 so I can make a portal in my Items layout. My portal uses the Items2 table with fields from such table. There are no filters on the portal. For some reason, the portal always shows one less portal row than the total number of Items table records (even as I add or delete records). Can't figure out why not all are showing in the portal. Any clues?
