Could you, please, let me know how to obtain the scalar for the value of the
column sum? I need the value I get using "egen sum(x)", but not the column of
these values, but just a single number which stata would terat as a scalar.
Use the return results from -summarize-. (See -[R] summarize- and -[P] return- in the manuals.) If you type

summ x
scal sidney=r(sum)

then the scalar -sidney- will contain the sum of x.

I hope this helps.
