Hello,
Let me preface this post with I’m a newbie and have limited programming background so please bare with me.
I have an Arduino uno with and ethernet sheild. I’m trying to get two temperature sensors to report to cosm. Over a year ago (prior to Cosm) I setup another identical setup using Pachube and its still functioning fine today. However using the same code does not work with the newly created FeedID. It gives me 403’s. I’m assuming its due to the new API version that must be required?
At any rate Cosm has example code they give and in trying to figure out how to get the example code to work for the new API I’m having all sorts of issues. It seems as though once I solve one compilation error another shows. Fun stuff 
However I’m now stumped and not sure how to proceed. Can you please help in identifying why I’m getting the following error when verifying the code?

The line of code that error is being generated on is - client.print(“PUT /v2/feeds/”);
Here is the current sketch
/*
Pachube sensor client
This sketch connects an analog sensor to Pachube (http://www.pachube.com)
using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
the Adafruit Ethernet shield, either one will work, as long as it's got
a Wiznet Ethernet module on board.
This example has been updated to use version 2.0 of the Pachube.com API.
To make it work, create a feed with a datastream, and give it the ID
sensor1. Or change the code below to match your feed.
Circuit:
* Analog sensor attached to analog in 0
* Ethernet shield attached to pins 10, 11, 12, 13
