assuming you've added the yes/no field to your table;

the set of data is the table - or a query that is a subset of the data; a
query is preferable because it allows you to sort the presentation and also
filter out the yes from the no.

you originally mention it being a subform;  you can insert a subform into a
main form with the subform being a table, a query or another form

I myself generally prefer a form - you can easily make a quick continous
form of the query using form wizard tabular....strip off the page
header/footer that wizard automatically creates and you have a simple form
that is ideal for use as a subform...

It is a continous form so the user is not looking at one record at a time -
one views all the records the query presents.   However you call it a subform
- and when you attempt to insert the subform the Wizard is going to prompt
you as to what is the logical link between the main form and subform... so
whatever relationship you establish can limit what is view..  this is very
fundamental database stuff...you can set there to be no link between the main
& subform and so the subform will show everything from the query regardless
of which record the main form is sourced on....

I hope this helps.
