Infopath saveas in sharepoint overwriting

Question

I need help getting an infopath form to not overwrite existing files going to a sharepoint library.

I have an infopath form with a custom submit. In the submit I am doing "me.saveas(http:\mysharepointlibrary\FormDropDownValue)

This is working just fine. But, if I create a new form and pick the same drop down value I can't get the form to not overwrite the old one. I also tried me.save() and me.submit(), both of those bomb.

I have the data connection set up to not allow overwrites, but it doesnt even seem to go into that connection to make the save. I think because of the custom submit code.

Any help will be greatly appreciated.
