database mirror job changed to use wmi escape macro - still got error

i have setup database mirror job and changed the job to use an escape macro - and i have selected the option to 'Replace tokens for all job responses to alerts' - The error I get is this: 'Unable to start execution of step 1 (reason: Variable WMI(StartTime) not found). The step failed.'

The job is:

INSERT

INTO dbo.[DB Mirroring State Changes]

(

[Event Time]

,

[Event Description]

,

[New State]

,

[Database]

)
VALUES
(

$(ESCAPE_SQUOTE(WMI(StartTime))),
'$(ESCAPE_SQUOTE(WMI(TextData)))'
,

$(ESCAPE_SQUOTE(WMI(State))),
'$(ESCAPE_SQUOTE(WMI(DatabaseName)))'
)
Does anyone know how to fix this???????????????????

The job code was this:

INSERT

INTO dbo.[DB Mirroring State Changes]

(

[Event Time]

,

[Event Description]

,

[New State]

,

[Database]

)
VALUES
(

$(ESCAPE_SQUOTE(WMI(StartTime))),
'$(ESCAPE_SQUOTE(WMI(TextData)))'
,

$(ESCAPE_SQUOTE(WMI(State))),
'$(ESCAPE_SQUOTE(WMI(DatabaseName)))'
)

ok - keeps getting truncated - here is the job code again:

INSERT
INTO dbo.[DB Mirroring State Changes]
([Event Time],[Event Description],[New State],[Database] )
VALUES($(ESCAPE_SQUOTE(WMI(StartTime))), '$(ESCAPE_SQUOTE(WMI(TextData)))',
$(ESCAPE_SQUOTE(WMI(State))),
'$(ESCAPE_SQUOTE(WMI(DatabaseName)))')
