[FLASH-USERS] Newbie Question: Adding Variables

Hi Trae,

My suggestion is simple: in your config file, you could change:

>   PARAMETER sim_crho  REAL  2

into

PARAMETER sim_crho REAL 2.

notice there's a dot at the end. Then you could try to resetup and compile as John suggested.

Best wishes,
Suoqing
