[ADMB Users] Circumventing a type mismatch

[Steve Martell]

Mark, 

Based on the definitions of the variables you have defined in the DATA_SECTION and PARAMETER_SECTIONS, it appears that your trying to overwrite data-type variables with values from the differentiable variables.  I would try in the PRELIMINARY_CALCS_SECTION or procedure section:

now_values=value(par_values);

the value function will allow you to overwirte a Data type variable with the values from the dvar_matrix.

A computer lets you make more mistakes faster than any invention in human history - with the possible exceptions of handguns and tequila....
