Your code shows you using the -recode()- function, which is quite different from the -recode- command. In Stata functions and commands are different!

I think that to comment helpfully we need to see more about your -hinctnt-, for example, the results of

. su hinctnt, detail

Your categories are not disjoint as (e.g.) the definitions [70, 120] and [120, 230] leave ambiguous what happens with 120. Alternatively, your notation here confuses the meaning of [ ] and ( ).
