Hello Everyone, I have a model which runs the calculate value tool: The code in the tool is: When the model runs the following errors are displayed: I'm not sure what the errors are related to. What's strange is that the code does seem to execute: it displays the extent of the site_polygon layer, sets the scale to 1:4000, then creates the JPG file. Any insights appreciated. Thanks! ...

Hello, I am working on a model and one of the steps executes a script (script is called AddLayerSitePolygon(2)). The purpose of the script is to: add a layer named "site_polygon" rename the layer to "PROPOSED - site_polygon" add a new layer named "site_polygon" The end result being that 2 new layers are added to the TOC ("site_polygon" and "PROPOSED - site_polygon"). When I watch the model execute I can see that the script works as I see the 2 layers get added to the TOC, but then right after they are removed from the TOC. Afterwards if I go ahead and run the script on it's own (outside of the model) it works as expected, the layers are added to the TOC and they stay there. I cannot figure out why it is that when the script is run within the model that the layers get removed from the TOC? Here is what the script looks like: import arcpy ##Reference the Current map document. #Add site_polygon mxd = arcpy.mapping.MapDocument("Current") df = arcpy.mapping.ListDataFrames(mxd)[0] NewLayer = arcpy.mapping.Layer("site_polygon.lyr") arcpy.mapping.AddLayer(df, NewLayer, "AUTO_ARRANGE") AddLayerSitePolygonResult = True mxd.save() #Rename site_polygon to "PROPOSED - site_polygon" for lyr in arcpy.mapping.ListLayers(mxd): if lyr.name in ("site_polygon"):   lyr.name = "PROPOSED - site_polygon" mxd.save() #Add site_polygon df2 = arcpy.mapping.ListDataFrames(mxd)[0] NewLayer2 = arcpy.mapping.Layer("site_polygon.lyr") arcpy.mapping.AddLayer(df2, NewLayer2, "AUTO_ARRANGE") AddLayerRenameSitePolygonResult = True arcpy.SetParameter(0, AddLayerRenameSitePolygonResult) mxd.save() arcpy.RefreshTOC() arcpy.RefreshActiveView() And here is a picture of where the script is in the model: Thanks for any help! ...
