I just checked it and it works OK for me
1) Make sure that the Excel File is closed before running the Import Command
2) Make sure the first line is TBC Excel
3) Make sure you save as a CSV File not a Mac of DOS CSV file
4) Format is P,S,O,Elev, Desc or S,O,Elev,Desc Desc is optional
5) When you browse the file list - if you right click on the file you can set the File Type there
6) At the base of the Importer - tell it whether you have a point ID or Not in the format being read
7) Choose Points or Sections
8) Pick the HAL
Eric is likely right - the R in the field will make that field Text not Numeric and that may upset the format interpreter unless that is being read as the Description field in which case that is not the problem
I tested it both ways and it worked with and without IDs
