st: Esttab: Dummy variable coefficient not found

Dear all,

I am running a simple ols regression with two categories of dummy
variables: one that refers to years (that I call yr1, yr2....until
yr59) and the other one that refers to an event that has occurred
(that I call yrs_event1, yrs_event2...until yrs_event58).

Now, the regression I do is perfect, but I cannot use the esttab
command as I get the following error messages: either "coefficient
yrs_event not found" or "coefficient yr not found".

In particular, I made the following:

esttab ols, drop(yrs_event* yr* o.* _cons) indicate(years  = yr3-yr59)
in order to have in the table the indication of whether year fixed
effects have been included or not, but Stata tells me that it can't
find the coefficients.

That is strange, isn't it?

Does anyone of you has any suggestion for why this is occurring?

Many thanks in advance,
