[Limdep Nlogit List] Crosstab command

[Alessandro Corsi]

This might be a trivial question, but I just installed Nlogi6 and I was 
trying to get a table givng me the frequencies of a discrete variable. 
As I always did with previous versions, I gave the following command:

CROSSTAB;Lhs=LEV_LET;Rhs=ONE$

but I received the message: Error    316: Crosstab: One of the variables 
is always <= 0 or >= 50.

Though, my LEV_LET variable is neither <= 0 or >= 50, as shown by Dstat:

DSTAT;Rhs=LEV_LET$

--------+---------------------------------------------------------------------

Descriptive Statistics for   1 variables

DSTAT results are matrix LASTDSTA in current project.

What is the problem? (BTW, I noticed that this version of Limdep does 
not seem to accept underscores in the variable names, even if they are 
reported with underscores in the variable list).

Thnks for any help
