I can see no problems in my example, Dani, so what is different in your
code?

***********
clear*

input byte month int year byte(x y) 
2 2010 2 3
4 2010 5 6
3 2010 3 9
2 2009 2 2
1 2009 3 9
end

expand 2, gen(id)
list, noo sepby(id)

gen mydate=monthly(string(month)+" "+ string(year), "MY")
form mydate %tmMonth_CCYY
tsset id mydate
***********

Subject: st: tsset for panel time series

Hi,

I'm trying to declare a panel time series and I'd appreciate some help. I
have data on several variables over time, as well as Year and Month
variables. I used -tostring- to convert Year and Month to string, and I
concatenated them into a third string variable (format YearMo). I then tried
to convert this third variable into date format using monthly(thirdvar,"ym")
and used it in tsset thirdvar and got an error message "repeated time values
in sample". I know I'm doing something wrong, but I can't figure out what or
how to fix it.'

Any help would be appreciated.

Thanks,

Dani Tilley
