Encountering problems with JSFiddle code - error-handling

Question

I have recently written a piece of code that checks temperature over a period of time for some course work. i wrote the program using different bits of code but cannot find the issue to some of the problems i am encountering.
I was just wondering if anyone can see any obvious errors that i am missing and could help out with some information int he right direction.
Link to the JSFiddle
//Counting the average temperatures in a day
//needs debugged!!!
var temperatures = [];
var total = 0;
function getCity() {
//get the locale to help with the display
city = prompt("Enter your city >> ");
}
function getNumDays() {
number = prompt("How many days in the study? Enter 1 - 10");
while ((number < 1) || (number > 10) ||( isNaN(number) === true)) {
alert ("Invalid input!");
number = prompt ("Enter again, 1 - 10 >> ");}
return number;
}
function getTemps(numDays) {
total = 0;
for (i = 0; i < numDays; i++) {
next = prompt ("Enter the temperature for day " + (i+1));
next = parseint(next);
while (isNaN(next)===true) {
next = 0;
next = prompt ("Error in input! Try again >>");
next = parseInt(next);}
temperatures.push(next);
}
total = total + next;
return temperatures;
}
function calcAverage(total, numDays) {
average = total / numDays;
return average;
}
function showStatistics(city, average, numdays) {
alert ("The average daily temperature for "+ city + " is " + average.toFixed(2) + " measured over " + numDays + " days." );
}
//main program
city = getCity();
numDays = getNumDays();
temperatures = getTemps(numDays);
Average = calcAverage(total, numDays);
showStatistics(city, average, numDays);

Answer 1

function getCity() {
//get the locale to help with the display
city = prompt("Enter your city >> ");
}
//main program
city = getCity();
Looks like you're missing a return statement.
Additionally, the line total = total + next; seems to be out of place: I imagine the total to be the total of the temperatures, not 0 + temperatureOfLastDay.
