Ok, that looks good.
This might be stupid, but according to this:
http://oss.oetiker.ch/rrdtool/tut/cdeftutorial.en.html
Your DEF lines should be of the format:
DEF:var_name_1=some.rrd:ds_name:CF
But in your case you have:
DEF:serverhttpbitsin=squid.rrd:IN:AVERAGE DEF:serverhttpbitsout=squid.rrd:OUT:AVERAGE DEF:numberofclients=squidclients.rrd:clients:AVERAGE
Where you seem to have an odd $ds_name
Where did IN, OUT, and clients come from? Your rrds says your ds names are numberofclients, serverhttpbitsin, serverhttpbitsout.
It seems this is your problem. Forgive me if it's not, I've only recently gained a rudimentary understanding of how CDEFs work, their complexity has overwhelmed me far too long than I care to admit.

Does your rrd have any data in it? (rrdtool dump foo.rrd)
