Hi,

I am running this query and the {{table1.selectedrow...}} bit is causing issues. If i plug float values into lat and lon it works though.

```
const getDistanceFromLatLonInKm = (lat1,lon1,lat2,lon2) => {
var R = 6371; // Radius of the earth in km
var dLat = deg2rad(lat2-lat1); // deg2rad below
var dLon = deg2rad(lon2-lon1);
var a =
Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(deg2rad(lat1)) * Math.cos(deg2rad(lat2)) *
Math.sin(dLon/2) * Math.sin(dLon/2)
;
var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
var d = R * c; // Distance in km
return d;
}
const deg2rad = (deg) => {
return deg * (Math.PI/180)
}
const lat1 = {{table1.selectedRow.data.destination_addresses['0'].location['0']}};
const lon1 = {{table1.selectedRow.data.destination_addresses['0'].location['1']}};
const lat2 = {{table1.selectedRow.data.location['0']}};
const lon2 = {{table1.selectedRow.data.location['0']}};
// const lat1 = 37.8136
// const lat2 = 33.8650
// const lon1 = 144.9631
// const lon2 = 151.2094
if (lat1 && lon1 && lat2 && lon2) {
return getDistanceFromLatLonInKm(lat1, lon1, lat2, lon2)
}
```
