Summarizing Treartment Types after polygon Intersect Arcade

I'm trying to summarize Proposed Action Treatment acres using the Implementation Treatment polygon feature using arcade. I have a layer of Proposed Action Treatments and a layer for Implementation Treatment units. When I click on an Implementation Treatment unit I want the pop-up to summarize the Proposed Action Treatment Type acres (there can be multiple). I'm having issues with my result variables, they are not displaying values just the words I'm putting in. I feel like I'm close but ran out of time and brain power to troubleshoot. Any suggestion on how to get the data results to appear in my pop-up correctly? Below is how the expression appears in the pop-up. Unit 9 ( in yellow) has 4 Proposed Action Treatment types. These are what I'm trying to summarize in the pop-up but I'm just getting the words and not summaries.

Here is my arcade expression:

//list proposed action treatments in an implementation polygon with acres.

//get the feature from Proposed Action Treatments layer overlapped by implementation polygon

var treat = Intersects(FeatureSetByName($map, "Proposed Treatments"), $feature)

//create a dictionary that stores the areas for each proposed action treatment type

var treat_areas = Dictionary()

//create a variable that stores the sum of all proposed action treatment areas

var treat_area_sum = 0

//set the variable to hold the total amount of area of the proposed action treatments within the implementation polygon

var treat_type_sum = 0;

//loop over the proposed action treatment polygons

for(var s in treat) {

//get the area of the intersection

var a = Area(Intersection($feature, s), "acre")

//add it to the sum

treat_area_sum += a

//store it in the dictionary

var type = s.Treat_Group

if(HasKey(treat_areas, type)) {

treat_areas[type] += a;

}else{

treat_areas[type] = a

treat_type_sum = treat_type_sum + 1;

}

//get some result info

var result = [

'The total area of the Implemented Unit is ${Round(Area($feature, "acres"))} Acres.'

]

//loop over PA treatment types and append area

for (var type in treat_areas) {

var a = treat_areas[type]

var p = a / treat_area_sum * 100

Push(result, '${type} ---- ${Round(p, 2)}% or ${Round(a, 2)} acres')

}

return Concatenate(result, TextFormatting.NewLine)

When using '${}' syntax, you have to use a back tick instead of a regular quote. This is called a template literal

Push(result, `${type} ---- ${Round(p, 2)}% or ${Round(a, 2)} acres`)

Thanks you! The back tick produced the result I needed!
