I have a Lutron FAELV-500M dimmer that says it is multi-location when used with a FA-AD accessory dimmer. When installed according to the schematic the FAELV will work but the FA-DA does nothing. What am I doing wrong? I have tried 2 different FA-DA accessory dimmers with the same results

There are two possible problems. Usually the FA-AD MUST go on the power end of the 3-way system and the FAELV-500M must go on the "switch leg" side of the 3-way system. If you have them reversed then the AD will not work because it does not always have power. The other option is that there may be a small "air gap" switch on the accesorry dimmer that disconnects power but usually that will make neither switch work.
