Navigation Form control syntax 2010

[AndycompanyZ]

I have a load of forms that now have been put into navigation forms using Access 2010 wizard. I know have found that most of the controls such as cascading comboboxes don't work and other comboboxes ask me for the parameter values when I open the form. I am unsure of the syntax for referning to these as I know the navigation forms are subforms and sonme of the comboboxes are in subforms themselves. I have as an example a combobox (cmboDepartmentID) that is asking me for the parameters whenever I open the formEvent ( through the navigation menu) this then has an unbound combox (cmboSubteamSF) on a subform (SubFormSubTeam). I have tried to work out the new reference but it isn't working so far I have as requery on the cmboDepartmentID:
Forms!frmMainNavigation!NavigationSubForm!Form!Sub formSubTeam.Form!cmboSubTeamSF.Requery but this doesn't requery and the combobox is blank. Can anyone point me in the right direction please.

Also the query for the subteam combobox will need changing I imagine as it is now:
SELECT tblSubTeam.SubTeam, ID
FROM tblSubTeam
WHERE (((tblSubTeam.DepartmentID) = [Forms]![frmEvent]![cmboDepartmentID]));
and that isn't referencing the right form either.

Solved the answer was:
[Forms]![frmMainNavigation]![NavigationSubform].[Form]![SubformSubTeam].[Form]![cmboSubTeamSF].Requery and i had to change the query to reflect the new reference too:
SELECT tblSubTeam.SubTeam, tblSubTeam.ID
FROM tblSubTeam
WHERE (((tblSubTeam.DepartmentID)=[Forms]![frmMainNavigation]![NavigationSubform].[Form]![cmboDepartmentID]));
