Importing Points

I have tried to import pointing into my Rover RS+ using reachview version 2.16.2 and I keep getting the same error message “At least one of the required columns is missing: Column “Elevation””. I have followed the template for .CSV, both importing the file and manually typing the text and I get the same message. Help - newbie here

Example of the text of a point I tried to enter: A,50.654933,-123.901667,686.00

FYI - the template shown on screen and the downloadable file example switch the order of the longitude and latitude columns. Does it matter which order the columns are in for importing?
