Banging my head against the wall

Question

I am working on a program to calculate bmi. I have input to read in age range and gender. When I enter input to look at both genders, it does not calculate the total patients or calculate the averages. Any help would be appreciated.
//prompts user for inputs
System.out.print("Enter the file name: ");
System.out.flush();
filename = console.nextLine();
System.out.println("What age range would you like to examine?");
System.out.print("Enter starting age: ");
System.out.flush();
agelooking = console.nextInt();
System.out.print("Enter ending age: ");
System.out.flush();
agelooking2 = console.nextInt();
System.out.println("What gender would you like to examine?\n"
+ "Enter F for Female; M for Male; B for Both genders: ");
genderlooking = console.next().charAt(0);
//reads in gender and age range
while (inFile.hasNext()) {
//read in gender
gender = inFile.next().charAt(0);
if (genderlooking == gender){
//read in age range
age = inFile.nextInt();
// filters logic for age
if(age >=agelooking && age2 <=agelooking2) {
totalpatients++;
//reads in height and weight
weight = inFile.nextInt();
height = inFile.nextInt();
//calculates bmi
bmi = (weight * weightkg) / Math.pow(height * heightm, 2);
totalbmi = bmi + totalbmi;
//takes bmi calculation and filters into 4 categories
if (bmi < 18.5) {
underweight++;
if (bmi >= 18.5 && bmi <= 24.9) {
normal++;
if (bmi >= 25.0 && bmi <= 29.9) {
overweight++;
if (bmi >= 30) {
obese++;
} //end while
//calculates averages
averagebmi = totalbmi/totalpatients;
averageUnderweight = underweight/totalpatients;
averageNormal = normal/totalpatients;
averageOverweight = overweight/totalpatients;
averageObese = obese/totalpatients;
//writing results to output file
outfile.println("Results of the BMI analysis for " + practiceName + ": \n\n");
if (gender == 'm' || gender == 'M')
Gender = "Male";
else
if (gender == 'f' || gender == 'F') {
Gender = "Female";
else
Gender = "Both";
outfile.println("Patients of " + Gender + " gender in age range of " + agelooking
+ " to " + agelooking2);
outfile.println ("Number of patients examine: " + totalpatients);
outfile.printf ("%.1f percent Underweight%n", averageUnderweight * 100);
outfile.printf ("%.1f percent Normal%n", averageNormal * 100);
outfile.printf ("%.1f percent Overweight%n", averageOverweight * 100);
outfile.printf("%.1f percent Obese%n%n", averageObese * 100);
outfile.printf("Average BMI: %.1f",averagebmi);
inFile.close();
outfile.close();
System.exit(0);
}

Because this line will never be true is you are looking for both genders, unless one of the records in teh file was entered as B for gender (Hermaphrodite?)
if (genderlooking == gender){
//Change that line to this
if(genderlooking == 'b' || genderlooking == 'B' || genderlooking == gender){
