Prescription rejected

I uploaded my script via MedXpress on Friday and was told my script was not accepted as it was missing my doctor’s practice number even though the script was from the same doctor that I have used previously - I would expect Discovery to have these details :-(. Nonetheless, I uploaded the top part of my script clearly showing the practice number and added a comment that this was for the prescription that was previously submitted. I then received a message from Discovery that my script was not processed as it was not clear. Please can you resolve this for me - you have all the information you need to process this for me. Thank you.
