Melanie,

You need a colon in the first line instead of an equals sign and -trim-
in the second line to get rid of an unwanted leading space. Try this:


. local date: display %td_CCYY_NN_DD date(c(current_date), "DMY")

. local date_string = subinstr(trim("`date'"), " " , "-", .)

. save "`date_string'_example", replace
