Once again, it is impossible to comment
on code you do not show us.
A simple example of the use of -egen, seq()-:
Let's set up 50 states X 50 counties X 10 districts:
set obs 25000
* we want 500 replicates of each state id:
egen state = seq(), block(500)
* within each state 10 replicates of each county
bysort state: egen county = seq(), block(10)
* within each county, ids 1 up
bysort state county : egen district = seq()
