Question : How to show line numbers in a query and add new records

I can get the following query to work and give me the correct line numbers every time, but, I cannot add additional records using this query
SELECT a.dfID, a.dfResultID, (SELECT COUNT(*) FROM tblDefect WHERE dfID<=a.dfID AND dfResultID= a.dfResultID) AS [Defect No]
FROM tblDefect AS a;

Can anyone please help me with a means of displaying line numbers in a query and on a subform whilst retaining the ability to add new records. I have also tried Microsofts GetLineNumber function - but I can only get that to work on a form and it doesn't always give me reliable results!!

Help is very much appreciated.

Answer : How to show line numbers in a query and add new records

GetLineNumber() is written to be used within a form, not from a query.

In your suform, add a text control to the form for the line number and set its controlsource to:

=GetLineNumber(Form,"dfID",[dfID])
