Thank you awfully much. I have somehow solved the issue, though I'm not really sure how. It seems that the recipress plugin doesn't save data to the database or something. When I changed "Instructions" to "Prescriptions", and even searched for the same in PHPMyAdmin, any I had entered were gone. When I re-entered them, the errors disappear. Surely it would be better to have an if/then statement so that if there ARE no "Prescriptions", nothing appears at all. Aw well. I'll work on that later I suppose.
Thank you all for taking a look at things.
