Hi,
sounds like an easy task for me,
BUT on the fly, I didn't find the appropriate Series IDs that matches your request. So can you deliver the IDs?
...and do you know, when the forecast-values are supplied? Are all 3 values delivert at the same time or is the forecast-value deleted after the current-value is announced?
So after clarification the work can begin.
