Subform Problem

[Jenny Lee via AccessMonster.com]

I have a main form with a subform in it the main form contains a close
command button. The trouble is that I can close the form without any data
in the subform, so I want have an error message to say that the subform
details must be entered before closing and then set the focus back to the
subform. Any Ideas?

Do you think

if Me.Dirty=False then... ?

might work?
