Preston -
I don't understand the 'all sub-forms run off the same query' I was
visualizing one main form with a subform, and you wanted to open another form
withing the margins of the subform. If you have multiple subforms, each with
the SAME query as a record source, then a better solution would be to have a
single subform that has multiple tabs to display the different portions of
the single query. This way the query runs once to populate all the tabs, not
one query for each tab.
It would be easier to understand if you gave us an idea of your data and
form structure, and what the needs are.
(FYI, I will be out of reach from early afternoon tomorrow through all of
next week, so it would be great to get this done today, or if it goes past
tomorrow morning, make a new post so someone else can help you out...)
