I built a model using model builder with help from this group (see this thread: https://community.esri.com/message/700561-re-repetitive-task-model-builder-or-python) but now I have a new problem: I can't open the model to edit the input and the output. I would like to get it to open in the model workbench (with the lovely flowcharts) but I get a blank window when I right-click--> edit or right click--> open.
I get the above when I open model builder first and then drag the tool into the window.
I'd really like to use my tool again if possible. The old thread has some things I've tried, but i'm hoping for some more input.
