Followed the documentation <A href="https://pro.arcgis.com/en/pro-app/latest/arcpy/geoprocessing_and_python/defining-parameters-in-a-python-toolbox.htm" target="_blank" rel="noopener">here</A>. In Pro 2.9.5, but that shouldn't matter for this.</P><P>I can get the value lists to show up, but I can't get any values to stick. Neither can I get the default values to work.</P><P>Would one of you be able to tell me what is wrong with this?</P><LI-CODE lang="python"> param17 = arcpy.Parameter( displayName = "Watermarks (Metadata)", name = "watermarkMD", datatype = "GPValueTable", parameterType = "Optional", direction = "Input") param17.columns = [['GPString', 'Dynamic Text'], ['GPString', 'Position']] param17.filters[0].type = 'ValueList' param17.filters[0].list =["GPSImgDirection","GPSCoordinates", "DateTime", "File Name", "Name Field", "Name Field 2"] param17.filters[1].type = 'ValueList' param17.filters[1].list =["Upper Left", "Middle Left", "Lower Left", "Upper Center", "Middle Center", "Lower Center", "Upper Right", "Middle Right", "Lower Right"] param17.values= [['File Name','Upper Right']]</LI-CODE><P>&nbsp;I can get the two columns to show up, and I can see the values in each list, but selecting them just makes them disappear.</P><P>This parameter is not affected by updateMessages(), and only turned off and on by a toggle in updateParameters(). I turned off that toggle functionality just to check and nothing changed.</P><P>I have checked, and I don't have two parameters named the same thing, which is normally the issue with this error.</P><P>I have also changed up the order of setting the default values/ the value list to match the documentation linked above, and that didn't change anything.</P><P>(Changing to all single quotes didn't help either. Ignore my inconsistent use of quotes please)</P><P>Basically, I'm out of ideas and am hoping some fresh eyes will catch something I've missed.</P> Thu, 28 Sep 2023 15:35:08 GMT https://community.esri.com/t5/python-questions/value-table-parameter-breaks-in-pyt/m-p/1333413#M68768 AlfredBaldenweck 2023-09-28T15:35:08Z https://community.esri.com/t5/python-questions/value-table-parameter-breaks-in-pyt/m-p/1333424#M68769 <P>Oh for Pete's sake.</P><P>I did actually have two parameters named the same thing.
