Rounding calculation fields to the nearest 500
I am a new user and a complete novice. I am using FileMaker as to keep track of real estate sales (I am an appraiser) and I have calculation fields set up to automatically calculate % of sale prices (e.g. 2%, 2.5%, 4%, 5%, 6%, etc.). I am looking to have the calculated results round to the nearest 500. Please advise and keep in mind that I am a beginner, lucky to have figured out the calculation fields....
