Hi, I have an script from 4 years ago & when I download the packages from [Archi-lab](https://forum.dynamobim.com/t/revit-2022-dynamo-2-10-package-not-showing-up-and-icons-missing/62933/7?) two nodes aren’t working. Can someone help me with this? Are there other nodes that I can use? Thanks in Advance ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/f/df29becb9fdfb1de76a5a054a531221739ce3a69.png) ---

Have you installed the right version of [Archi-Lab](https://forum.dynamobim.com/t/revit-2022-dynamo-2-10-package-not-showing-up-and-icons-missing/62933/7?)? See the linked post for more info, but the last two digits of the version number you install needs to match your Revit version. ---

Hi @Caj or try familyinstance by curve from clockwork and for levels think genius loci have some great nodes for that ---

Thanks! It worked. ---

Is it safer to use that node? Or are both not a problem? ---

no one should be a problem, for archilab that package is very version specific, but works as a charm with the right version… ---

I’m now getting the error: Object reference not set to an instance of an object. Do you know how to fix this? Is the family not good? ---

I can’t share it, because It’s a detailed structural family from our company with a lot of information in it. A few years ago this worked fine. ---

What is the data coming into the node? Try putting an Object.Type node before each input and join those into a list (List.Join + List.Flatten) and look for unique object types. You should only have FamilyType, Line, and Level in that list. If it has a Null or other object type you’ve got bad data to start with. If you are really doing structural framing I recommend using one of the constructors for Structural Framing that are out of the box (Dynamo’s core library \> Revit \> Elements \> Structural Framing \> one of the nodes next to a green line). ---

What do you mean by Object.Type? I tried that but it says the same. The input for Line & Level is good. Only the Family Type is giving an error, but that’s weird, because the input is an Family Type node. Unfortunately I can’t use Structural Framing nodes. ---

Oh I’m sorry. It’s the level node. It’s not picking the right level name from Revit. ---

Dynamo gets the level from a linked model, but I don’t have that level in my project file. Is there any tool to get it on the right level? ---

> [@Caj](#): > > Is there any tool to get it on the right level? We can’t help efficiently without seeing more, and it’s not really related to the original topic. Please start a new topic and provide some screenshots of what you are seeing. A minimally reproducible dataset may be required to troubleshoot as I haven’t see what you’re describing so it’s tough to troubleshoot. Try opening the model detached and delete 99% the work including all views but one and all materials, then purge unused and save as a new file. If you can’t post the model even with that degree of cleanup start a new model from no template and reproduce the issue. if you can’t reproduce the issue with a new file then it’s something related to how your model has been built not anything to do with Dynamo or particular nodes.
