Try checking the numbers it shows. If it is e.g. 12/10 it means that the recipe requires 12x capacity of something, but that only 10 are available. If that is the case, you might have to add more machines of the required type to the factory. It is also possible that you've got insufficient resources of the required type. They must be added to the red box besides the workbench inside the factory. It can't use materials placed outside of the factory.
