Interesting. What are you trying to do in plain English? There may be options. What is your database about? Please show us your table designs.
From what I can gather, your database isn't normalized. You have the data in the top portion which should be stored in one separate table, and then the subrecords below which would be stored in another separate table, linked to the first table using the ID number.
If you insist on keeping your structure, your form would need to use VBA code to store your data in that manner.
