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?</SPAN></BODY></HTML> Wed, 18 Jan 2012 17:29:32 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/weighted-overlay-problems-with-the-influence/m-p/624467#M9089 BrianBoisvert1 2012-01-18T17:29:32Z Re: Weighted Overlay: Problems with the % Influence https://community.esri.com/t5/arcgis-spatial-analyst-questions/weighted-overlay-problems-with-the-influence/m-p/624468#M9090 <HTML><HEAD></HEAD><BODY><SPAN>The problem is solved by downloading service packs 1-3 when using ArcGIS 10.</SPAN></BODY></HTML> Thu, 19 Jan 2012 15:45:54 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/weighted-overlay-problems-with-the-influence/m-p/624468#M9090 BrianBoisvert1 2012-01-19T15:45:54Z
