I have a form with a collection that allows a file upload.  HR will use this form to upload documents for multiple employees.  When saving the attachments to the repository I want to be able to associate the employee number for an individual record in the collection as metadata for that record's uploaded file.  I've tried this:

{/dataset/MyCollection/Employee_Number}

but it stores all employee numbers from the collection into each record's uploaded document.  I've also tried this:

{/dataset/MyCollection/Employee_Number[Row(0)]}

but it stores nothing in the metadata.

Is there a way to do this?

Thanks!
