Requerying subforms in tab controls

[Jenni]

I currently have a query that is joining two distinct pools of
information and turning them into one records with a unique identifier
This query is dependent on criteria passed from a form in a number of
text and combo boxes. This part of the form works fine.

On Open a Tab control is displayed but the subforms in each of the
three tabs are hidden until the required info is gathered from the
user. The subforms are then displayed, emphasis given to the first
tab which can display a number of records. What I want this tab
control to do is display the other tabs, the information pertaining
only to the record selected in the first i.e. setting some kind of
filter to say that [ID2]= Forms!MainForm!Subform.Form!Control.

I have tried this in two ways, neither of which have been completely
successful. The first tab is based on the same query as the main form
and returns all the records that match. The second tab is based on
the same query with a filter something like that above - no joy.

Secondly I replicated the query and merely added and additional query
like the filter above. This does produce the required result for the
subform cannot be requeried so as users flick through the available
records on the first tab, the second tab remains on the initial record
unless Shift+F9 is used.

I have tried The Requery Statement Forms!Mainform!Subform.Form.Requery
is the OnCurrent event of the first tab, the AfterUpdate event of a
control on this tab, the onCick event of the second tab top and
finally I tried passing the ID to a text box in the main form and then
requerying on the AfterUpdate event of this control - nothing
requeries the form other that Shift+F9. So I tried the Send Keys
commands on all of the above Events and again nothing.

I an absolutely 100% stumped and about 5 minutes away from scrapping
and starting again. Hopefully someone has some dawning inspiration.

P.S I have tried experimenting with the syntax of both the Requery
statement and filter but according to both here and the help, as is
should be fine.

Thanks in advance for any help
