Using Combine function of ArcGIS Spatial Analyst?


I am trying to use the combine function on ArcGIS 10.3 for Desktop.


I have two raster files that have the same values and I want to combine them in order to compute an accuracy assessment through excel.


However whenever I compute the combine command I end up with a blank attribute table. I have checked to make sure they are in the same coordinate system, they are the same size, overlap, and have the same values to match up.



Does anyone know what the issue may be?
