Attempting to modify industry data

Implan guru's. I am working with the Hawaii model and attempting to modify it to better represent a different island economy. I have modified all the industry data to what I want and then re-constructed the model. Now, however, my multipliers are messed up. Something I have done has now modified the induced effects to teh point where many of them are negative. Similarly, my indirect effects are now very low with the end result that my total effects multiplier are in a range from 0.97 to 1.05 Note, when modifying the industry data, I did unlock the intermediate effects as I edited industry totals for employment, output and the value added categories. My best guess is that I have not changed the final demand categories - I notice that my total value added has changed - which affects total final demand - but that the categories of final demand (households, government) have not changed. And it seems that, to make up for the extra spending needed, imports have increased significantly. So what do I need to do to rebalance things??
