I am trying to create a new map on arcgis online.  In the past, I have used zipped shapefiles via the "add layer from file" feature.  Today, when I try that, I am getting an error message, "Unable to import this shapefile. (Generate Features exception 'null')".  I have zipped the appropriate files together (shp, shx, dbf, prj) into 1 zip file.  I reviewed my attribute table and found no entry with "null". 

What am I doing wrong?

Are there other parts of my files that I need to correct or change?

Many thanks in advance,
