Your image didn’t post. Try again and make sure you have all your data visible in the node preview bubbles. The error is telling you that you’re providing a string value when the parameter is not a string. I’m guessing your parameter takes a number but you’ll have to confirm that yourself. There are custom nodes for dealing with circuits (MEPover and [OpenMEP](https://forum.dynamobim.com/t/openmep-package-feedback-thread/) are usually good options to start with) or you can always use Python and the Revit API to do exactly what you’d like.
