As @ToanDN stated ,in order to tag or schedule a parameter it should be a shared parameter or Revit default parmater.
If you are using the same parameters of the door (that are working),then the problem might be a duplication of the same name of the parameter .I recommend to delete and add again from your shared parameter list.
Also if you can share the family we may help you better.
