Wifi shield not mounting/connecting- Freetronics Eleven, Wifi Shield R3

HI Everybody,

I am using a Freetronics Eleven (alternate version of the uno here; http://www.freetronics.com/products/eleven#.U-GIekD9zuc and an official Arduino Wifi shield R3.

When attempting to use the sketch below, serial monitor says the Wifi shield is not connected and does not proceed. I have proved the wifi shield etc is working by uploading the Arduino IDE 1.0.5-R2 Xively>WifiDatastreamUpload sketch which connects to the network and does not give the shield not mounted error.

The sketch is for an aquaponics system.
The Eleven is powered via the Micso USB
The link light on the wifi shield comes on using the xively example sketch but no lights at all on the wifi shield when using below sketch.
Connecting to a WPA 2 network.
I have left the Float and Void Loop sections out of the code i have posted.

Can you please help me solve this issue.

Thanks

You can’t use D7 or D10 to D13 for anything on an Uno if you are using the WiFi shield.

int LevelSwitch3 = 13;

Ah damn. So simple. Thanks heaps. Wish I could provide more input into this great site but my skills are currently minimal. I'll keep spreading the word but :)
