Ethershield Simple Client

 Hoping to use Trystan's 'Ethershield Simple Client DHCP Pachube' but can't get the formatting correctly presented.

The usual Pachube csv format is;

data1, 100
data2, 323
data3, 89 

but the template code delivers 221.0,236.0

dtostrf(a0,0,1,fstr); strcat(str,fstr); strcat(str,",");
dtostrf(a1,0,1,fstr); strcat(str,fstr);

Can this be formatted so that it updates a Pachube feed.
