So, the code I am using is below. It all works, except for the last part where it is supposed to go through and find the highest number out of a set of five. At the moment, it just choses Monday and the amount of books borrowed on that day. It is not going through the other amounts and comparing them. So, can anyone help and show me what I have missed out?

var booksArray = new Array (5);
var dayNamesArray = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'];
var maxBooksIndex;
document.write('Array program to read in a known number of books borrowed over five days');
for (var day = 0; day < booksArray.length; day = day + 1)
{
booksArray[day] = window.prompt('Enter number of books borrowed on ' + dayNamesArray[day],'')
};
document.write('<BR>' + '<BR>');
document.write('Confirmation of data input' + '<BR>' + '<BR>');
for (var day = 0; day < booksArray.length; day = day + 1)
{
document.write(dayNamesArray[day] + ': ' + booksArray[day] + '<BR>')
};
maxBooksIndex = 0;
for (var day = 1; day < booksArray.length; day = day + 1)
{
if (booksArray[day] > booksArray[maxBooksIndex])
{
maxBooksIndex = day;
}
};
document.write('Maximum number of books was ' + booksArray[maxBooksIndex] + ' and this was on ' + dayNamesArray[maxBooksIndex])

What browser are you using. I tried in Firefox 2 and IE6 and it worked for me in both.

I looked over the code and I don't see anything that looks wrong either. From what I can see it should be working.

Ok, that's odd. I will try it in another browser then and see what happens. I am using mozilla firefox ver 2.0.0.4

Edit:- I tried it in another browser and it is still choosing Monday and the number of books borrowed on that day. These are the numbers I am entering for each day: Monday - 9, Tuesday - 1, Wednesday - 1, Thursday - 23, Friday - 0. So, it should be choosing Thursday and the number 23, but it isn't. Anyone got any clues?

Edit2:- I tried it with a different set of data (5, 7, 21, 3, 9), in this case it is supposed to pick Wednesday with 21 books, but it picks Friday with 9 books. It doesn't seem to like numbers with two digits??

Solved it *dances round room*.

I had missed out a parseFloat part. Thanks for any input anway. Always appreciated.

Glad you got it working. I admit I didn't thoroughly test it so maybe I just got lucky with the numbers I tried. Sorry I couldn't help more, but still glad you got it all sorted out.
