Hi Guys;


Using RRDTOOL on a Windows based system, for the 1st Time, working on
the Tutorial, and discovered an error message and would like someone to
help resolve asap Shown below:


C:\wamp\www\rrdtool\rrdtool-1.2.27-w32>rrdtool graph speed4.jpg --start
920804400 --end 920808000 --vertical-label km/h
DEF:myspeed=test.rrd:speed:AVERAGE "CDEF:kmh=myspeed,3600,*"
CDEF:fast=kmh,100,GT,100,0,IF CDEF:over=kmh,100,GT,kmh,100,-,0,IF
CDEF:over=kmh,100,GT,kmh,100,-,0,IF CDEF:good=kmh,100,GT,0,kmh,IF
HRULE:100#0000FF:"Maximum allowed" AREA:good#00FF00:"Good speed"
AREA:fast#550000:"Too fast" STACK:over#FF0000:"Over speed"

ERROR: Attempting to reuse 'over'


it seems it does not understand 'over' in the IF ELSE statements:
over=kmh ,100,GT,kmh,100,-,0, CDEF:over=kmh...


Best Regards,
