st: Problem with grqreg

["Michael C. Morrison" <Morrimic@niacc.edu>]

I'm having a problem with grqreg.

After running a quantile regression with:

    sqreg  pincp  ageqtr retp schl_group semp sex wagp, q(.05 .10 .25 
.50 .75 .90 .95)

I want to graph the coefficients of the quantile regression with grqreg 
with the following command:

    grqreg, ci ols

However, I receive the following error:

    postfile: variable ageqtr already exists
    r(110);

(Note that "ageqtr" is the first independent var in the quantile 
regression.)

All my variables have labels.

Any help would be greatly appreciated. I'm using Stata version 11, 64 
bit, Windows 7.

Mike
