Javascript date object/increment notes field

[DoctorGonzo]

Hi guys,

similar topics have been covered before, but none have helped me really.

I simply want to prompt user with "number of days", and whatever the user types in is captured. A date object on the field is then incremented with/by this number. No matter what I do I get "object does not support this property or method". Bah! I'm used to this message!

Anyway, can anyone please help me with this code?

Many thanks,

Gonzo

function ExtendTheDate(){
var dateday = prompt("Please enter number of days to increase expiry date by","")
if (dateday != null && dateday != "")
{
alert("This Will increase date object by " + dateday + " days!");
document.forms[0].DateToChange.setDate(document.forms[0].DateToChange.getDate()+ dateday);
}

I'm a bit out of practice with JS, so I can't really help, but I'm guessing your problem is with this line:

document.forms[0].DateToChange.setDate(document.forms[0].DateToChange.getDate()+ dateday);

Use comments and a process of elimination to determine if this is truly the source of your problems, and if it is, try this instead:

var inc = document.forms[0].DateToChange.getDate()+ dateday
document.forms[0].DateToChange.setDate(inc);

Just an idea - putting things in variables sometimes solves little glitches like this. Sorry if its no help, but I tried!
