Count of empty field in portal

[Ron Cates]

Hi all. I have a portal on a layout with summary fields above the portal that gives me the total number of records and a summary of another field in the portal. Now I need to be able to have a field above the portal that can give me a count of records in the portal where a certain field is empty. Can anyone give me an idea on how I can do this?

Thanks

Try something like =

Count ( Child::Matchfield ) - Count ( Child::Certainfield )
