I applied the script that was suggested in my other question (viewtopic.php?f=28&t=17825) - which seemed to go well.
Except for an oddity with the 'indoor temp' values. These seem to be picking up another value.
Transposed values are as follows..
Apparent is showing values for Dew Point
Inside is showing values for Apparent
I followed the instructions in Beteljuice's script to the letter.
Anyone else have a similar problem.
