A Invalid Input error message pop out when creating a flange family following Revit MEP 2010 Families Guide - Metric Tutorials.
Please help to figure out the reason.
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.
