Hi Rachel,
I just had a look at your xslx file and now I see the problem. It appears you are using several geopoint questions all in the same layer, this is not supported. As per ArcGIS feature layers, there can only be one geometry field. Each geopoint question (or geotrace or geoshape) is a geometry field, so you can not have more than one in the same layer.
If you want to use more than one map question (geopoint) to collect data, you need to put them in seperate layers, via a repeat, or you can use the "null" esri field type, so that the question can be used in the survey, but the data/geometry not stored in the feature layer.
Regards,
Phil.
