SetParameterByName doesnt take doubles?

Revit

Hi all,

I’m trying to push parameters to Spaces via Element.SetParameterByName

At first I tried with dummy list and it worked.

After i pulled a list from excel and tried to push it to the same node i got an error:

Warning: Element.SetParameterByName operation failed.
The call is ambiguous between the following methods or properties: ‘Revit.Elements.InternalUtilities.ElementUtils.SetParameterValue(Autodesk.Revit.DB.Parameter, Revit.Elements.Element)’ and ‘Revit.Elements.InternalUtilities.ElementUtils.SetParameterValue(Autodesk.Revit.DB.Parameter, string)’

My first and second scripts:

Does it mean that Element.SetParameterByName doesnt take doubles as inputs for ‘value’? Or am I doing something wrong?

And how would I push parameters that arent round numbers to Elements in the future?

Thanks to everyone in advance. My first post, hope I’m not missing something too obvious

It looks like you probably have a null value. You’ll have to replace your nulls with something else.

I did miss a null. Thank you
