st: Variable in bootstrap program not found

["Nelson, Carl" <chnelson@illinois.edu>]

I am writing a bootstrap to obtain standard errors after two-step estimation with a generated regressor. When I try to execute the program I receive the following error.

 use full_inv, replace
. capture program drop twostepseboot
. program define twostepseboot, rclass
  1. version 10
  2.

  6. foreach c of local coeff {
  7.         scalar b`c' = _b[`c']
  8.         return scalar bs`c' = b`c'
  9. }
 10. drop mun_res
 11. end

. 
. twostepseboot
[technical] not found
r(111);
When I run the code through line 8 as a do file and add scalar list I see all the b`c' and bs`c' variables have been created, thus I am puzzled by the error message.
And insight would be appreciated.
