LTspice - Error!

  1. Feb 24, 2010 #1
    * C:\Documents and Settings\****(myusername)\Desktop\project\projectSimulation.asc

    .tran 0 1 0 .1m
    .backanno
    .end

    The above is my code. My .lib statement correctly imports and uses the 1n4004 diode I found. However, the subcircuit representing my 1N5231B Zener keeps giving me this error:
    Fatal Error: Unknown subcircuit called in:
    xdz 0 vout 1n5231b


    Here are the contents of the 1N5231B.lib:
