Dynamic Table

Dynamic Table

I would like a user to be able to submit multiple attachments through an input form and then display those attachments in a dynamic table. After the form is submitted with 1 to 10 attachments I run analysis and organize them as metadata like this: Metadata.attachements.url & Metadata.attachements.url_label.  My problem is if I have multiple attachments the dynamic table does not seem to support an array or possibly more than just that. 

Is there a work around here I am missing?
