Hi,
There are a few discussions on this topic but I'm not finding the solution I need or it is right in front of my face and I'm missing it completely.
I'm using Desktop 10.3. I'm am trying to create a geoprocessing tool with the input dialogue box requesting the user to select:
1. Feature class e.g US States
2. Field with the States name in the Feature Class e.g. stateNames
3. A drop-down of the 50 states where the user can select one of the states.
I'm trying to use the python toolbox tool template (portion shown below). I'm able to populate a drop-down of the fields and now need to have the user select a value from the field.
Any suggestions?
Thanks
Brian
