Dear Adebola,

see this Stevenīs message:

http://www.stata.com/statalist/archive/2008-08/msg01377.html

Do you svyset your data again with the new stratum variable?

I think that you can use idonepsu to do this too...

help idonepsu

Hope this helps,

Joao Lima

I found 5 single sampling units, combined them with ones preceding them but this still doesn't fix the problem when I check it again. What am I doing wrong and how can I fix this?
