Access Automating text input into MS Access subform

[wintersilke]

I have automated 2 text files (space delimited) to be imported into a MS Access form. I have no problems getting the correct info into the main form but am having trouble getting the 2 subforms to accept the text correctly. The both subforms have a primary and secondary index and the text inputs into the first secondary index and then overwrites the same secondary index. This isn't described really well but it is like I cannot get the secondary index to advance.

Can anyone help on this?
