If is null

[deb]

I have a form fTLNo with a subform called fWS
fTLNo has a text field called TL

Now..
On the subform fWS I have a date field called RecDate.

If TLNo on the main form is not null, I must also have the RecDate populated
on the subform.
Please help.

it seems like you did not complete what the question is about...

if fTLNo is an integer you can use >0 or otherwise Not IsNull( )

not clear when the decision is made.... on the main form - or subform....
