Thread: New fields similar to image fields where a file can be downloaded

New fields similar to image fields where a file can be downloaded

I'm new to Wordpress & ClassiPress and not familiar with all the functionality available.
I was trying to set up a customized field where my users could place a "preview" of their digital item they are selling, but the only field types are text & drop down. Is there a way to add a new field where the user to could attached a file??? How about if they want to place a paypal Buy Now button in their add - can this be done? Thank you!!
