Andrew-
You should never store a calculated field like this in a table. I assume you're using a form to edit POHeader and a subform to edit POLines. Make the subform a Continuous form and put a text box in the form footer:
=Count(*)

Hi All,
Can anyone help with this one.
I have two tables POHeader & POLines, and the POHeader table has a field that keeps track of the number of line items. I need a query that will update the NumLineItems field in the POHeader table with the correct count for the number of Line Items for that POHeader record, if you see what I mean. I can easily do it using VBA, but I'm sure it could be done using a query, but I can't quite get it to work.
Any help greatly appreciated.
Thanks,
Andrew
