how to set data in a field in a sub-form from the form??

[virginie]

i have a sub-form in a form
i want to lock a field in the subform according to a condition from the principal form.
i try :
If commitdate.Value <> &quot;&quot; Then
supply.Locked = True
// this works : this field is in the principal form
order_details.descr.Locked = True
//this dont work : order_details is the subform name and descr is the field name i want to change

how can i access this field from the princpal form?

When you are in the main form and want to reference the sub form you must fully qualify the name.

Forms![MainForm]![SubForm]![descr]
