ID in sub form

[jasdMeco]

Hi everyone,

I have a [Form1] and a [Sub Form2]. This sub form contains the lines of the
[Form1].

I want to put automatically in each line of the sub form a sequential ID [1,
2, 3, …]. And this ID restarts of the zero for each new record in [Form1].

Post the SQL for the source of [Sub Form2].
