I have an excel sheet with three columns in it that i want to use. One column is frequency. This column is just you basic counts so 10,12,14, etc, etc...and they import fine. The other column are rates. The numbers in this column contain decimal points and for some reason they all show up in ArcMap as <Null>. I have tried looking for spaces in the data, changing the column type to "General" and "Numeric" and "text" and they still show up as <Null> how do i get them to import correctly?
