r-class results get overwritten by results from the next r-class
command, and -log- is one such. Look at the help for -log- to see
this.

In your case you can save the results after -summarize- to use them
when needed.

su date, meanonly
local min = r(min)
local max = r(max)
log on
di "Old ORN - NO Activities - NEW sample - ALL rooms - " %tdd/N/CY
`min' " to " %tdd/N/CY `max)' " - NO package"

In this case

local min `r(min)'
local max `r(max)'

or

local min "`r(min)'"
local max "`r(max)'"

or any combination would work as well.
