Conditional Formatting of a subform within a subform

[Marc T]

Hi,

am pulling hair out trying to get this to work!

I hvae a nested form as below:

frmMainBrowse
frmMainComboBox
frmData
frmManualEntry

I have fields duplicated between frmData and frmManualEntry, and I am
wanting to set the field within frmManualEntry to enabled = no if the
corresponding field within frmData is not blank.

I think I'm getting confused by referencing between the two!

This seems to work within the conditional formatting box if I open frmData
as the main form:
[Forms]![frmData]![DT_PLANNED_START]<>" "

I can't get it to work if I open the frmMainBrowse form though. Any clues as
to what I'm doing wrong? Also, am I better trying to go via VB code?

Any help would be much appreciated!
