Hello all, I am trying to get a list of elements that have a certain element type but I always get this error and I tried alot of things and tried searching online but couldn’t find any solution. Your kind help is highly appreciated. Thanks. ![Screenshot 2023-06-14 203859](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/8/083a70b8316d733e344f5a332badf62ea606500a.png) ---

Hi @eslam.abdo.taha . The node “All Elements of Type” expects a System Type, the node is used to get all walls, roofs, etc. If you’re working with FamilyTypes use FamilyInstance.ByFamilyType. ---

Thanks @Daan for your response. Unfortunately, I am working with element type, not family type. ---

You made duplicates with a new name so there are no elements of the same type? ---

@pyXam It’s an RNC conduit that I duplicated and renamed it according to data in an excel sheet ![Screenshot 2023-06-15 064018](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/d/cd9807dbbb06e5d7201295800ad356dea8534c54.png) ![Conduits2Cables_2023-06-15_06-41-34](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/3/53eaaf4891588b04f912a5b28389e7d3e23ac91c.png) ---

We’re you doing this in the UI or in Dynamo? How were you attempting to do either? ---

Hi @eslam.abdo.taha you have duplicated a type and think then you try to write to an instance parameter, it isnt possible before the type have an instance…but probably something here could give an idea… ![Capture](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/3/4/34b2c4571d772730e372a327464c54f53a8a33f6.png) ---

OBS Pay Attention to Lacing. ---

Hi @stefan.gokstorp not 100 sure thats the issue, i think user try to write to an instance parameter as when he try connect directly elementype to set parameter it doesnt work… ---
