Hello everyone,

Could you please help me with the node ‘Element.SetParameterByName’? I’ve got the warning, that operation is failed and no parameter found by that name…

What am I doing wrong? I was following this tutorial: [https://www.youtube.com/watch?v=eRzWUCReqkc](https://www.youtube.com/watch?v=eRzWUCReqkc)

Also, I send my Dynamo and Excel files.

Here is a link to the Revit file: [https://drive.google.com/file/d/1fi0mAyaW1nESy4zIKto9xctCORaNvyXE/view?usp=sharing](https://drive.google.com/file/d/1fi0mAyaW1nESy4zIKto9xctCORaNvyXE/view?usp=sharing)

Thank you very much in advance!

Hi @Alena1503,  
It’s because the parameter names that you have created in Revit don’t match the names that you are providing in Dynamo.  
 ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/9/49a5436b8161e3ba09c82dfda963fe82ccf2bb1e.png)

i.e. Parameter **CRN Clash X** is **NOT EQUAL** to Parameter **Clash X**  
or even Clash **N** ame is **NOT EQUAL** to Clash **n** ame

**Parameter names are character as well as case sensitive.**
