Hi all,

My name is Marcel and currently I’m stuck on a challenge for checking values from Revit and Excel and writing the updated values from Excel into Revit.

I’m got a model with at least 395 rooms, which have all been numbered in the past (based on the number parameter, which is an instance parameter in the file).

And I’ve got an excel file with sort of the same room numbers.

My first step was to identify the rooms by checking the list through boolean values. Based on the “number” parameter and the room numbers I’ve got a checking mechanism in place which tells me if the rooms are true or false and therefore are corresponding with each other.

So far so good, but the next step is to write the excel data based on the list.sort node into Revit (filtered on an instance parameter). Except the “Set parameter value by name” is related to the “Element” data type. And the sorted list I’ve got as an output, which paired the objects provided me with a string output. This does not match, and gives the error shown in the image below.

Can someone help me with this?

Much appreciated.

Marcel
