r(2000) no observations in the dfuller unit root test

[Marouen Amiri]

Hi,
I am new in the forum, i would like to find a solution for a problem that i encountered once i am testing the stationarity of the time series. Here is the code and the error message:

dfuller dow, lags(0)
no observations
r(2000);

It may be noted that the variables are all of numerical type (float).
Thanks in adavance for your help.
