Cynical Weather summary different to icon

Hi Perry,

Firstly, thank you for all the plugins and the support, for an Indigo newbie, all your posts are really helping me learn.

I'm working on a control page that will include some weather information. I noticed that the summary can differ to the icon. For example, summary says 'Mostly Cloudy' but the icon is calling for 'partly-cloudy-day' which means I always get a partly cloudy graphic instead of a mostly cloudy one.

Apologies in advance if this a really stupid question ! Am I doing something wrong ?

Thanks very much,

Andrew.
