Daniel, Your previous message did not state that you had a "variable not found" error. Section 3.3 of the Statalist FAQ advises: "Say exactly what you typed and exactly what Stata typed (or did) in response. N.B. exactly! If you can, reproduce the error with one of Stata's provided datasets or a simple concocted dataset that you include in your posting." Does your loop produce the variable names that you need? You can check by adding -display- commands to the loop, as I suggested in my last message. display "`k'" display "Q1170_0`year'" display "Q0`k'_0`year'" You can also use -confirm- in combination with -capture- to execute commands only for variables that exist in your data. sysuse auto, clear foreach var in mpg weight xyz { capture confirm variable `var' if !_rc { sum `var' } } Friedrich On Fri, Nov 21, 2008 at 6:35 AM, Daniel Schultz <schultzd@tcd.ie> wrote: > Sorry for not mention the error. > I thought that the error message is clear, due to my description. > The error message is, that a variable is not found.
