Need Help Debugging JavaScript

Can anyone figure out the coding error that I have in this if/then statement?

if (gender1 ==='Feminino') {
if(age1 <= 15){ f_kids++;} else if (age1>15 && age1 < 60 ){f_ adults++; } else if (age1 > 59 ){f_seniors++;} else{empty++;}
} else {
if(age1 <= 15){ m_kids++;} else if (age1>15 && age1 < 60 ){m_ adults++; } else if (age1 > 59 ){m_seniors++;} else{empty++;}
}
I would like to use this in a Qualtrics survey to calculate the total number of female "Feminino" adults, kids and seniors from a previous question where the respondents enter in the name, age and gender of the individuals in the household. I eventually want to use the code to make these calculations for up to 15 household members - just testing the code for the first household member here.

I first set the variables to zero (before the code above)
let m_adults = 0;
let f_adults = 0;
let f_kids = 0;
let f_seniors = 0;
let m_kids = 0;
let m_seniors = 0;

and before that I read in the responses:
let age1= parseInt("${q://QID8%232/ChoiceTextEntryValue/1/1}");
let age2= parseInt("${q://QID8%232/ChoiceTextEntryValue/2/1}");
let age3= parseInt("${q://QID8%232/ChoiceTextEntryValue/3/1}");
let age4= parseInt("${q://QID8%232/ChoiceTextEntryValue/4/1}");
let age5= parseInt("${q://QID8%232/ChoiceTextEntryValue/5/1}");
let age6= parseInt("${q://QID8%232/ChoiceTextEntryValue/6/1}");
let age7= parseInt("${q://QID8%232/ChoiceTextEntryValue/7/1}");
let age8= parseInt("${q://QID8%232/ChoiceTextEntryValue/8/1}");
let age9= parseInt("${q://QID8%232/ChoiceTextEntryValue/9/1}");
let age10= parseInt("${q://QID8%232/ChoiceTextEntryValue/10/1}");
let age11= parseInt("${q://QID8%232/ChoiceTextEntryValue/11/1}");
let age12= parseInt("${q://QID8%232/ChoiceTextEntryValue/12/1}");
let age13= parseInt("${q://QID8%232/ChoiceTextEntryValue/13/1}");
let age14= parseInt("${q://QID8%232/ChoiceTextEntryValue/14/1}");
let age15= parseInt("${q://QID8%232/ChoiceTextEntryValue/15/1}");

let gender1= ("${q://QID8%233/ChoiceGroup/SelectedAnswers/1}");
