I have a mail form with radio buttons and was wondering how can I make sure one button is checked. For all my other text fields I was able to do a check similiar to what I have below and it works great to make sure no blank entries were entered in the mail form. But how would I do a validation check on radio buttons? My radio input data does NOT get validated in my below script area. So I assume radio inputs such as these have a special way of getting validated? 

<input name="color" type="radio" value="red"> 
<input name="color" type="radio" value="green"> 
<input name="color" type="radio" value="blue">

Script part that works with text data: 
foreach $field (param) 
{ 
    foreach $value (param($field)) 
    { 
        if ($value eq "") 
        { 
            #blank values ..give user a message here etc..  
        } 
    } 
}
