I was trying to extract multiple value to point. It always shows generic (99999) error. I checked projections of all file (shape file and raster) and all are in same projection(LCC_2SP) with NAD83 datum. I tried reprojecting all files into another projections, nothing worked out yet. I tried 'sampling' tool as well. No luck so far. However, 'Extract values to point' tools works just fine with those raster individually.
