I am following the instructions and have add to display set, model parameter set, add results to geoprocessing checked. The only thing that I can't do with the described steps is the manage option. It is grayed out and I do not know how to ungray it so I can check it. Have help would be appreciated
Managed only applies to intermediate datasets. The reason for that step is to keep intermediate datasets in your model (datasets between two tools) from being deleted at the end of the model tool run, which was happening to Candace.
