I am trying to write a prescription file (.pre) for my flexicoil task controller. It is giving me a communication error (prescription error) when I try loading it on the task controller. I think it might be a problem with my prescription file and the supplies portion of it. When I load the shape files back into farmworks for a double check the product id's come back as a_1, a_2 and a_3....is this normal? Would you be able to help me out? Perhaps take a look at my files to see if there would be an problem with them?
