beginning click combine combined combo deal deals don download enabled file files help individually inventory items package packaged packaging products sell show single together trial uploaded variants

I am beginning to sell here - still in my trial, but can't seem to figure out the packaging deal. I have all my products uploaded individually, but when I click to make combo deals, only part of my items show up to choose from.

Any help?

Package items use files and can affect inventory. Thus items which have single file download or inventory enabled and which don't have "variants" enabled are the only ones which can be packaged together.

Thanks - you're right! I was trying to combine items, and then combine the combined items.
