Changing Condition Options

[tallowbay_high_velocity]

I am trying to list a used Cot bed but the only option to select is new condition. Does anyone know why this is and how it can be changed to show all options?

I believe it is because you cannot sell second hand child cots on eBay, they have to be new, hence that's the only option available.
