Virtuemart Attachment Plugin with j3 + VM 2.9

Thank you for the reply. I saved the product before selecting the file. The procedure was:

-Create the prodcut
-Select the custom field
-Save the product
-Get in the product again and select the file with browse button (was a PDF), insert a name and click "Save and exit"

I think the procedure was right but if i enter the product again i see that no file was uploaded. I also think that the system actually upload the file (it takes a bit to save the product) but then it don't show as custom field..

thank you for your help!

Hello, is there a way to make this plugin work with Joomla 3.3.3 and Virtuemart 2.9?
Plugin install with no problem but when I select a file to upload and click "save" notihing gets uploaded and a new file is not added to the product.
Thank you
