Ok, since you don't need help with any of the other code, and you say that you just want to know how to use a -tempfile- to do a merge, here is a example that you can adapt to your dataset:


****************!
sysuse auto, clear
tempfile one two
save `one', replace

keep if rep78 > 3
save `two', replace

use `one', clear
merge 1:1 make using `two'
****************!

See -help tempfile- for more help.
