Your first check was:

isValid=!empty(date(1999,lnMonth,lnDay))

This will handle Feb 29th as well as any other date. For example:

? date(1999,2,29) && returns empty date
? date(2000,2,29) && returns {02/29/2000}

Basically, provided his spinners make sure the month is between 1 and 12, and the day is between 1 and 31, your simple one-liner is a most elegant solution...

If I am still missing something, or if I misread the original post or yours, let me know! I love date stuff! *smile*
