I'm trying to set a price for a purchase field so I want to select 'fixed' then add the value but it is stuck on 'user input' and when I try to select the 'fixed' the following message is returned 'The selected price type is not valid for the purchase field. The changes will be reverted' why is this happening? How can I add the values to my items?
What type of field are you trying to map? A choice field or number field? It seems like you are trying to map a number field which wouldn't be possible. You can only assign a fixed value to choices. Number/currency fields are for user input.
