Dear Statalisters

I want to run an OLS employing weights given by the
data providers to account for its statified sample
design. They suggest issuing the following

.gen wpstr04=cell_no if cell_no<=17
(1945 missing values generated)

. replace wpstr04=(cell_no+1) if cell_no>=18
(1945 real changes made)

. recode wpstr04 (11/12=13) (17=16) (19/21=22)
(25/26=27) (36=35) (37=38) (40=41) (44=43) (59=60)
 (64=65) (82=83) (107=108)
(wpstr04: 154 changes made)

. svyset [pweight=empwtnr], strata(wpstr04)

      pweight: empwtnr
          VCE: linearized
     Strata 1: wpstr04
         SU 1: <observations>
        FPC 1: <zero>

where empwtnr=employment weight 

Then I run 

svy: regress y1 x1 x2 x3 (running regress on
estimation sample)

This is what I get

Mata run-time error

I would be grateful if anyone would let me know how
one can rectify the above error message and run the

Many thanks
