Is there any way to sum the values returned from the below expression, I cant figure it out. Thanks in Advance
var floodplain = FeatureSetByName($datastore, "RES_FLOOD_HAZARD")
// Get FeatureSet of intersecting flood zones
var flood_fs = Intersects($FEATURE, floodplain))
// Instantiate output string
var out_str = 'Flood Zone Acreage:'
// Iterate over FeatureSet
for(var f in flood_fs){
// Get intersection, calculate area
var xs = Intersection(f, $feature)
// Calculate acreage
var a = Areageodetic(xs,'acres')
// Append to output string
out_str += `\n${f.fld_zone} | ${a} ac`
}
return out_str
