Excel to Revit, How do Element.SetParamenterByName work

Hi I am stuck cant assing new mark vaule to My doors in Revit. It reads the Excel but the Element.SetParamenterByname will not Write the new mark values to the door .I tried to Place numbers in value as well but it did not work either.

“Mark” parameter expects a string - currently the values you have are integers. Use a “String.FromObject” node to convert the numbers into strings (text) and then feed into “Element.SetParameterByName”.

Alternatively - you could toggle the “ReadAsStrings” boolean from the ReadExcel node.

Thanks that worked great
