Problems with GPRINT (LAST, MAX AND A

[Wildcat]

Hellow!

I getting statistics from the number of dial users connected to my machine using ucd-snmp mib and GET SNMP DATA in Cacti.
Works fine only with area values.:
Item #1 users_machine AREA 8D85F3 [Down], [Up] Remove
But.. when I try get the LAST, MAX or AVERAGE values with GPRINT.. the graph show me only the word "nan"
Item #2 users_machine: GPRINT [Down], [Up] Remove ]

I updated my cacti version to 0.6.8 and it doesnt works.

Anybody knows what happening?

Thanks and sorry for my poor english. `

How long did you wait before giving up on the GPRINT's? Sometimes it takes 2 or so gathering periods before any real numbers will show up. Also, I am curious about what cacti is seeing. Click 'view source' next to one of the graphs that is not working (with a GPRINT of course) and post that source to this thread.
