[rrd-users] Problems with rrdtool graph (does not represent a number)

Hello guys,
I'm having problems trying to execute the "rrdtool graph" command. When I
execute the command RRDtool gives me this error:
*ERROR: parameter 'a' does not represent a number in line
AREA:a#FFF200:Unicast Packets In*

"*a*" is "*DEF:a="/var/www/ferramentas/restrito/temp_rrds/TRAFEGO-
10.173.255.28_41.rrd":Trafego_in:AVERAGE*"

And at the rrd file I have:

<ds>
                <name> Trafego_in </name>
                <type> COUNTER </type>
                <minimal_heartbeat> 15 </minimal_heartbeat>
                <min> 0.0000000000e+00 </min>
                <max> NaN </max>
</ds>

I'm trying to make a graph of a 10 seconds step rrd, the update command is
working but the graph command is not..

Can someone help me? Does anyone knows what is this problem?

#RRDtool 1.2.15#
#Debian etch    #

Thank you,
