Thanks Kalle. I had no problem making the change to replace the 'C' with 'Degrees'.
However, I'm really struggling with the other changes. I don't have any (significant) experience 'coding' and have tried putting the variables into line 2 (I wanted to leave the ones I'm using ('Current Weather Format', '0' and '3') but without success. The problem is that I don't have experience with the use of the 'curly' brackets, where to put commas and the meaning of 'C.' or 'D0' etc.
If you do one of the two lines that I've requested, I'm sure that I could figure out the other one!
Also, it would be REALLY useful if there was a table in the Forum that had the 'Conditions', 'Forecast' and '10 Day DATA' that showed :
1. the variable as it is set out in the drag and drop window
2. the actual code as it then appears in the box once you drag it into one of the 4 options
3. a description of the variable as to what it does
4. an example of the variable in a string in one of the options
5. the actual result of the variable (i.e. what comes out when you press 'test'
