I'm new to using model builder and have to do a nested iteration (for every month I have to iterate through 6 parameters). I am thinking of doing that by using nested models. One model doing the interation through monthes and then providing the current month as parameter to the submodel that iterates through the 6 parameters.

The linking of the models does not work correctly (boxes are not colored). How can I make the current month value available to the submodel? I just want the month parameter to be available in a function; I don't connect it to a function as input variable.

Your help would be greatly appreciated.

Thanks, Lea

If you provide a screenshot/graphic of the model-in-progress, you will likely receive more specific advice. –  Aaron Sep 17 '12 at 20:14
    
I have had some success working with nested models and iterators. If you provide some graphics that would greatly help understanding your question. –  eric Sep 17 '12 at 20:42

You have to make it ModelParameter see pics.

And then you can add this variable in first model.
