incorrect graph for interface

[alittle]

I am trying to graph only selected ports off a switch. So, when i select say the index for slot 10 port 26, it graphs for slot 10 port 2. It appears to happen on any index I select where under Name (IF-MIB) slot is listed as a 2 digit number (ie, slot 10, slot 11) Any thoughts? I am currently running 0.8.6h
