Javascript cookie "Type Mismatch" solution

I have some javascript ASP code that sets the expiry date on a cookie
to five years from now. The code worked until today, when I got the
following error message:

Microsoft JScript runtime (0x800A000D)
Type mismatch

The code was

var expiryDate=new Date();
expiryDate.setYear(expiryDate.getYear()+5);

Response.Cookies(cookieName).Expires=DateToExpires(expiryDate);

function DateToExpires(myDate)
{
return
String(theDate.getMonth())+"/"+theDate.getDate()+"/"+theDate.getFullYear();
}

DateToExpires returns "4/31/2010"; this is the correct format for
Expires.

See the problem? APRIL HAS ONLY 30 DAYS! I forgot that the value of
theDate.getMonth() runs from 0 to 11. The proper code is

function DateToExpires(myDate)
{
return
String(theDate.getMonth()+1)+"/"+theDate.getDate()+"/"+theDate.getFullYear();
}

which returns "5/31/2010" (which is actually 5 years from now!)

I hope that this helps someone.

myDate and theDate ? Re-check your object names.
