Is there a script which will pick up the highest number from a collection of numbers? the users will enter in numbers into seperate fields and i need to pick up the highest number.

any clues?

Just loop through all the numbers and keep a record in a variable of the biggest number you've seen.

More generally, this site is a great resource for javascript snippets: http://www.irt.org/script/script.htm

I'm thinking:

- Put the numbers into an array
- Set variable "highestNum" to 0
- For each element in the array as "x"
- Check whether x is greater than highestNum
- If true, highestNum = x, continue to next array element
- If false, highestNum stays the same, continue to next array element

When you reach the end, highestNum should contain the largest number.

Sorry it's not actual javascript here (haven't touched that stuff for years).
But the logic is all there. :P

var numbers = Array ("1", "5", "3", "4", "2");
var highest = 0;
for ( x = 0; x < numbers.length; x++ ) {
if ( numbers[ x ] > highest )
highest = numbers[ x ]
