When I try to use Multi-buy with Donation Product and no donation amount is entered, the customer is able to click add all to cart and is redirected to their cart. If the customer enters any amount and then clicks to add all to cart they get the following error: "Please enter a description." There is no where to enter a description.
I have Donation Product with the ability to enter any amount working perfectly as a stand-alone product else where on my site.
Any ideas?
