what is the error message?

Hi sorry for the late reply I have been away
The Fabrication Part Dimension says: Error: Custom node not loaded
The Aw Number.To String says: Warning: Method ‘__func_7138be89af7b4232b938e63a5fe78240()’ not found
The Element.SetParmeterByNAme Node says: 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)’

been playing around and now got the Fabrication Part Dimension Node to say: Warning: This custom node contains an invalid input. Please fix the input before saving the custom node.

Sometimes it seems to work if I do a force run?
