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 class tool(object):     def __init__(self):         """Define the tool (tool name is the name of the class)."""         self.label = "tool"         self.description = ""         self.canRunInBackground = True     def getParameterInfo(self):        # first paramter         in_feature = arcpy.Parameter(            displayName = "Feature with States",            name = "in_feature",            datatype = "Feature Layer",            parameterType = "Required",            direction = "Input")         stateField = arcpy.Parameter(            displayName = "Field with State Names",            name = "stateField",            datatype = "Field",            parameterType = "Required",            direction = "Input")         stateField.filter.list = ['Text']         stateField.parameterDependencies = [in_feature.name]         stateName = arcpy.Parameter(            displayName = "Select one State",            name = "stateName",            datatype = "GPValueTable",            parameterType = "Required",            direction = "Input")       return     def updateParameters(self, parameters):         """Modify the values and properties of parameters before internal         validation is performed.  This method is called whenever a parameter         has been changed."""         return ...
