No Link Arrows in Your Query?
If you are missing a link to arrow next to a field you would normally expect to see an arrow, you must have forgotten to put...
FOR BROWSE
...at the very end (bottom) of your query.
Additionally, if you do not use FOR BROWSE in your query and you attempt to create a Print Layout Designer (PLD) report from that query, you may find that there will be no field descriptions for the fields.
