Could someone show me how to make something like this in a python toolbox as well as explain to me what is going on here? I know that the user can select either a table or a feature class and this dialog box will create a list of the fields with check boxes. One question I have is when the user checks the fields and clicks OK, does it make a list of the checked fields or does it do something else? The code below is a close as I've gotten to the above image, even though I know  all it does it let you select a single field from the list of fields. Any help would be much appreciated. Thanks!         # Third parameter - User will select the parcel ID field         parcelID = arcpy.Parameter(             # Name that shows inside the tools dialog             displayName = "Select the Paracel ID field",             # This variable puts the displayName over the input             name = "parcelID",             # Accepts a field as input             datatype = "Field",             # Have to enter somthing before the tool can run             parameterType = "Required",             # It's an input to the tool             direction = "Input")                         parcelID.parameterDependencies = [existingData.name] ...

I am trying to write a script that that changes the aliases of a table's fields, but when I ran it I got this code error: ExecuteError: ERROR 001601: Failed to alter field alias. Failed to execute (AlterField). This makes no sense to me and I would love any input as to why this happened. Also, here is my code that generated this error: # Import geoprocessing import arcpy # Set workspace arcpy.env.workspace = r'U:\newberry\new.gdb' # Creates a list of fields from the Metadata_2010 table fieldListTable = arcpy.ListFields("METADATA_2010") # Creates a cursor - a data access object rows = arcpy.SearchCursor("METADATA_2010") # Creates an empty table to store row values fullNames = [] # For loop thats iterates through the rows in # the Full_Name field of the Metadata_2010 table for row in rows:     # Adds the row value to the fullNames list     fullNames.append(row.getValue(fieldListTable[2].name)) # Creates a sliced list of fields from the census block group # polygon feature class fieldList = arcpy.ListFields("please")[2:630] # For loop thats changes the existing alias name in the table # to the name in the fullNames list for i in range(len(fieldList)):     arcpy.AlterField_management('please', str(fieldList.name),'',str(fullNames)) ...
