Once making the changes that Bert suggested to reflect the Plan section, you've deleted and added meds. Go to the medication history (below the window for Social history and Allergies). Then place the cursor somewhere in the medication box and hit the <delete> key. A window will popup tell you that you can't edit meds from this window. Click "yes" to the question and the prescription writer will come up. Then simply close out of the window and it will repopulate the Medication history window to reflect the current changes.
