Hello, I'm tyring to pull through information on habitats from habitats layer within the Site Boundary feature (as $feature) in this pop-up expression. So far it has been working fine when hard coding the Baseline_habitat_Type to match the expected values in the 'habitats layer' features, but i am now developing it to read the unique 'baseline_habitat_type's from the features that intersect and run a for loop off this, any help would be greatly appriciated as to why this is producing the result:

Result Value

Result	[ 0 - 0 ha , 1 - 0 ha ]
Type	Array

var habs = Intersects( FeatureSetByName( $map,"Habitats Layer",["Site_Code","Baseline_Broad_Habitat","Baseline_Habitat_Type","Baseline_Condition","Shape__Area"]), $feature) //variables var intcount = count(habs) var expr = '' var areaString = '' var outArr = [] var outArr_index = 0 //generate unique habitat types array var ListHabs = [] var ListHabs_Index = 0 for (var hab in habs){ ListHabs[ListHabs_Index] = hab.Baseline_Habitat_Type ++ListHabs_Index } var UniqListHabs = distinct(ListHabs) if (intcount > 0){ for (var UniqListHab in UniqListHabs){ var UniqListHabArea = 0 for (var hab in habs){ if (hab.Baseline_Habitat_Type == UniqListHab){ UniqListHabArea += hab.Shape_Area } } outarr[outArr_index] = UniqListHab + " - " + round(UniqListHabArea*0.0001, 2) + ' ha' + TextFormatting.NewLine ++outArr_index } expr = Sort(outarr) } else{ expr = 'No Baseline currently mapped or uploaded for ' + $feature["Site_Code"] } return expr

Do you want the output to be a string of the values in the expr array? If so, then just use the Concatenate function

expr = Concatenate(Sort(outarr), ", ");
