[Gretl-users] importing data

I really have problems to import data in gretl. I red the manual and respected the folowing contraint for CSV files - NA string for missing values (I also tried with blank cells and single dots) - header with no more than height characterters - no number in the headers, no space - no header for the column of observations code I tries with different data files, with xls and dta files. Gretl always reply that he can't open the file. So what's the problem ? ___________________________________________________________________________ Nouveau : téléphonez moins cher avec Yahoo!
