@Michael & Andy
You gents where correct, it was adding a newline to return data.
console.log( '[' + data + ']' );
showed the correct data being returned. After looking at my php
script I did have a few blank lines before/after <?php ?>. Removed
these and everything is working great now!!
Can not believe it was something stupid like that!
Thanks for your help!!
