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
