Reply To: number of resources doesn't change

I think I don’t understand your answer.
What can I do if I want to make a reservation of 8 items but the panel only shows 1? I think it must offer to select the number of items available for each resource: if one resourse have 8 items the panel must let me choose from 1 to 8, If I select another resourse with 24 items, from 1 to 24, and so on. This is not like this so I think this is a bug, and I’d like to fix it. Please help.
Thank you
