"Forecasting with RM Series"

Hi everybody,
I am working with the RapidMiner Windowing operator, in order to forecast the value of a company's revenue in the future.
The dataset contains a value per month, so that I used a window size of 12. However, I am not able to know which the values are going to be for 3 months in advance. I thought the "horizon" parameter was the one to choose how many time-units in advance to forecast, but this didn't work.
For example in Weka, this step is pretty easy. In my case, I should just select 3 in the parameter "Number of time units to forecast". However, I guess in RapidMiner this is not that straightforward.
What should I do in order to forecast the values in the future (let's say 3 months)??
Thanks in advance
