[ARW VISIONS]

Used this. Also put it in a separate JS file so it would be global.

function validate_form(){
if (document.orderform[4].selectedIndex=='0')
 {
    alert('Please select whether you would like to use New Measurements or My Measurements.'); 
    return false; 
 }
 else if(document.orderform[4].selectedIndex=='1')
 {
            var elem = (document.orderform.elements);
            var nelem = (elem.length*1) - (3*1);
            
                for(var i = 0; i < nelem; i++)
        {     
            
                 
                 if(document.orderform[i].type=='select-one')
                 { 
                         if(document.orderform[i].selectedIndex=='0')
                         {
                               alert('Please select all options.'); 
                                        return false;
                                }
                        }
                    
        }         
 }
else return true;
}
