Hi there,
If the Cost drop-down menu is greyed out, it usually means one of the following:
Network Dataset Not Built Yet
Make sure you’ve run the Build Network tool after defining your attributes.
Without a built network, some UI elements remain inactive.
Missing or Misconfigured Attribute
Go to the Attributes tab in the Network Dataset Properties.
Confirm that your cost attribute (e.g., Minutes or Meters) is listed and properly configured.
Evaluator Not Set
In the Evaluators tab, check that each source (e.g., Streets, Streets_Override) has a valid evaluator for the cost attribute.
If it’s set to “None” or the field is missing, the drop-down will be disabled.
Missing Field in Source Data
Make sure the source feature class has a field with valid numeric values for the cost (e.g., travel time or distance).
If the field is empty or missing, the attribute won’t activate.
Once these are set up, rebuild the network and the drop-down should become active.
