It seems that you entered "Lena2" as searched column, the real column name in the CSV file is LenA2. Please try change the column name accordingly. By the way, I saw you enter 0' for default value, please also change it to 0 mm.
Please also make sure the file "M_Generic 1 Mpa Slip Flange.csv" is copied to Lookup table folder. The look up table folder could be found in Revit.ini file, by the following clause:
LookupTableLocation=<lookup table file path>
On my computer, the clause is LookupTableLocation=C:\ProgramData\Autodesk\RME 2011\LookupTables, so my lookup table files are located in C:\ProgramData\Autodesk\RME 2011\LookupTables. ______________________________________________________________
