You will be asked to pick the latitude and longitude from your data set. Epicollect5 prepends "lat_" and "long_" to latitude and longitude column respectively.
We are using the EC5 Demo Project for this example so we will pick "lat_3_Where_are_you" as the latitude and "long_3_Where_are_you" as the longitude.
Now you will be asked to pick a colum of your data set to be used as the title for the placemark. Epicollect5 conveniently has a "title" column assigned to each of your entries (learn more about entry title) therefore that is an obvious choice.
