Form select values based upon another form field?

[Victor]

I'm somewhat new to javascript and I have a form with drop-down selection fields for 'month', 'day', and 'year'.

For example, if someone selects 'February' as the month, I don't want 29 (unless it is a leap year), 30 or 31, to be listed as available options in the 'day' field.

The information will be validated on the 'server-side', but I would to catch it on the client-side.

Any assistance or pointers to online resources to explore this is appreciated.

Thanks!

http://www.javascriptsource.com - they have a similar script there involving the choosing of a Continent, then a Country, etc...you may be able to learn from that.
