editable fields and inserting new rows

[BriEric]

I am new to portals but I've seen someone do what I am trying. The idea is a portal with multiple rows within which are fields which the user will enter data, ie. Quantity, Price, etc... Once one row has been completed the portal will add another row of editable fields. I've experimented with this but while I can get the portal to use editable fields, I can't get the auto insertion of a new row once the first is complete. Any ideas?

When you define the relationship there is a check box: "allow creation of related records". You need to check this box.
