Haversine Issue

[genesiusj63]

Hello, 

I am working with a GPX file and installed the haversine app to calculate the distance between lat/lon coordinates in each event. This is the latest 

index="gpx" source="11.22.20-Long-7.5.gpx"
| eval tlat='trkpt{@lat}' | eval tlon='trkpt{@lon}'
| haversine originfield="tlat,tlon" outputField=d lat lon
| table trkpt.time, trkpt{@lat}, lat, trkpt{@lon}, lon, d, trkpt.ele

I know I am missing something so minor, but I can't see it.

Thanks in advance for any assistance you can provide here.

Safe and healthy to you and yours.
Happy and Blessed Thanksgiving,
Genesius
