Navigation forms

[liamfitz]

Is there a reliable reference, for referencing 'subforms' values/controls therein. The following doesn't work

If Forms!frmNavigationLeft.Form!NavigationSubform.Form!frmClients.Cnam <> "" Then

As you can see I'm trying to check a Public variable (Cnam) on a subform. I have a navigation form (frmNavigationLeft), 'on' which is another navigation form ( frmNavigationTop) 'under' these nav. buttons I have several forms. how do I erefr to controls/values I know there's a particular format, but it's not quite right. Any help appreciated. thanks.

If you have left the standard naming of the navigation control subforms then:

Forms!frmNavigationLeft!NavigationSubform!NavigationSubform!Cnam

Thank you for your prompt and helpful response.

That works well, but I can't figure out, how to pass a vaule from a field on a subform of that Form i.e I have a subform on the last Form referred to in your command
Forms!frmNavigationLeft!NavigationSubform!NavigationSubform!sfrmReferrals.Referral_ID

I have put a field, which is on the mainfrom, instead of 'sfrmReferrals.Referral_ID' this works, but as you see I also wish to take a value from the subform( field = Referral_ID ), and the above syntax is wrong. Any help much appreciated.
