Trying to use "iterate Datasets" to run multiple OD Cost Matrices. The "Iterator Datasets" isn't picking up my network datasets, meaning the first is not recognized in the iterator output, and no file name is stored in the "Name". I can't continue to make the model as the "Make OD Cost Matrix Layer" tool won't accept the placeholder "Dataset" as the input, and I can't set any parameters without an input. I've tried this with both shapefile derived ND's and geodatabase derived networks. Any ideas?
