Weighted Overlay: Problems with the % Influence

Hi all,

I've been working on a suitability analysis and am using the weighted overlay tool to do so. When I try to manually enter the % Influence, I recieve "ERROR -1 Sum of the % influence doesn't equal 100," however, the sum of influence does say 100 and a manual calculation confirms this. When I click OK and close the tool and reopen it (within model builder) the % Influence numbers change. If I use the Set Equal Influence, I get results, but these don't reflect what we feel is important. Any ideas?
