Help creating folder action to duplicate files

[VLSI]

Please could someone help an Automator novice! I need to immediately copy into folder B any file that an application saves to folder A. I've experimented with creating folder actions but I can't make them watch the folder successfully - I have to manually run the action for anything to happen. I've looked at tutorials but none that show this being done in Sierra. Perhaps you could walk me through the steps?
TIA
VLSI
