Form Validation Question

Form Validation Question

Hello All,

I'm a bit stumped on what the best way to validate my form that I have built out.

Here is the form. http://pretendcity.org/temp/asq/index.html

This is what I need it to have do:

1. If the user select "My Child is older than 5 1/2" the form should decline.
2. ZIP code has to be one of the ones I have from a list I was given (about 50 ZIP codes)

I cannot figure out how to do both, I was told to do the ZIP by passing it through with an array but I'm not too familiar with jQuery or java (im a graphic designer).

Any help would be greatly appreciated.

Thanks to all!
