WHEN <> 4 OR 6 OR 12 PRINT "ERROR"
ENDCASE

The parameters to WHEN are a constant expression, just like any other constant expression. What happens if you do:
PRINT 4
PRINT 6
PRINT <> 4 OR 6 OR 12

Often the simplest way to start debugging a piece of code is to PRINT each of the parameters and see what happens.
