FX9500 RFID Reader Command Line feature in Web Console

I am using the "Command line" feature in the Web Console on the FX9500 RFID reader and I in put the following:

reader.set_pwd(admin, blah, XXXXXXXXXXXXXXX) the x's represent my 15 character password, when I hit enter I get the following error:

error.parser.unknown_variable.  I try different ways to input it but still get the same error.  Is there something I am missing?  Thank you!
