I have created a model that has an optional input for start times (time of day) for an OD Cost Matrix. I have two check boxes, one for am rush (8:00:00 AM) and one for pm rush (5:00:00 PM). I am trying to get the start time as an input to the OD Cost Matrix but am unsure of how Boolean code would work. Here is a photo of what I have so far. I am cringing asking this because I know I am being unclear... I just can't formulate the proper question?
