Check spelling, “03 Buildig Type” ?? Also I agree with @Johannes_Meiners pretty sure Project Info elements don’t have a Sheet Number parameter to set. Also, what is coming out of each get param value node? Lastly, the error of the set param node is not presented for others to know, understand or offer thoughts.
All parameter are shared parameters that i created
and the error is:
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)’
