Additional question regarding validating numeric fields

Question

This is part of the code i obtained in order to check validation.
//var reg = /^\d+$/; // checks whether input contains ONLY digits
var reg = /\d+/; // checks whether input contains digits AND letters
However, i found that both options checks only wether input contains letters.
What is the function that checks if input contains only digits ?

Hi,
This is an example of where FormCalc has an advantage over JavaScript. There are built in functions in FormCalc for getting the maximum and minimum values.
In the total mileage, you could set up two variables, one for Max and one for Min and then subtract them.
var maxMiles = Max(mileage[*])
var minMiles = Min(mileage[*])
$ = maxMiles - minMiles
This is based on the script being in the calculate event of the total field. Also it depends on how you have set up the table. If the rows have the same name: eg Row1[0], Row1[1], Row1[2],... Row1[30] and the mileage field is named the same in each row, then the script may look like:
var maxMiles = Max(Row1[*].mileage[*])
Hope that helps,
