Hello,

I know this is simple (in fact I think i've done it before, but can't remember how, and can't find the old code). Does anyone know the syntax for validating input from the tag of a form? For example, if I had something like this in a form:

Select a color
red
blue

How can I use javascript to check to ensure a choice was selected? Thanks.

Bob

Hello,

Thanks to anyone who was going to help with this, but I remembered myself. You can use:

if (document.formName.fieldName[0].selected == false &&
document.formName.fieldName[1].selected == false){
alert("You must choose one option");
return false;}

Thanks,

Bob
