>>The number I am trying to get is 1.3.6.1.4.1.2021.4.6.0 +
1.3.6.1.4.1.2021.4.13.0 + 1.3.6.1.4.1.2021.4.14.0 and graph this on the
Green.  Then I want to graph 1.3.6.1.4.1.2021.4.5.0 on the blue line.  I
just cant make the target line work.

OID maths works on pairs of numbers.
So Target[total]: OID1&OID2:public at IP + OID3&OID4:public at ip will plot
OID1+OID3 as green and OID2+OID4 as blue (or have I got the colours the
wrong way round?)

So you need to find two more OIDs to use on your blue line. Find something
guaranteed to return zero every time and use that.

Alternatively, plot each pair seperately, store the answers in RRD format,
and let Routers2.cgi do the totalling for you (still need the extra blank
of numbers, to make up three pairs)

Peter
