Steel Sector - 171

Mr. Moderator, thx for your quick responses to my questions. I have another one for you. I'm modeling the operation of a facility using a national model. I estimate that the total direct dollars spent in the steel sector (171) is about $71M. When I analyze the steel spending (plus the rest of the spending totaling $160M for operations), the direct number shows up as $71M in the foreign trade sector (25,001). Could you explain why this might happen and how I could fix it so it shows up as direct expenditures in the steel sector? I've been modeling national numbers for awhile and haven't had a problem. I made a few changes in assumptions yesterday (not much) and it changed the results. Your insights would be appreciated.
