The "Please choose..." is selected by default. I want the user to be forced to choose one of the four below it.

<select name="product">
<option selected>Please choose...</option>
<option>product 01</option>
<option>product 02</option>
<option>product 03</option>
<option>product 04</option>
</select>


The caveat is that I'm already using two onsubmits and an onclick:

onSubmit="return (Require(this,'Name') && submitonce(this))"

onclick="return checkit()"

Here is the js for the them:

Code:
// Check for a valid email address

var testresults
function checkemail(){
var str=document.formCheck.Email.value
var filter=/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i
if (filter.test(str))
testresults=true
else{
alert("Please input a valid email address.")
testresults=false
}
return (testresults)
}

function checkit(){
if (document.layers||document.getElementById||document.all)
return checkemail()
else
return true
}

// Check for required fields

function Require(obForm,szFields)
    {
      var fields = szFields.split(",")
      var szMissing= new Array();
      for (x=0;x<fields.length;x++) {
        if (obForm.elements[fields[x]].value.length==0) {
           szMissing[szMissing.length]=new String(fields[x]);
        }
      }
      if (szMissing.length) {
        alert("The"+((szMissing.length>1)?"s ":" ")+szMissing.join(",")+" field must be completed.");
        return false
      }
      return true;
    }

// Check for multiple submissions

function submitonce(theform){
//if IE 4+ or NS 6+
if (document.all||document.getElementById){
//screen thru every element in the form, and hunt down "submit" and "reset"
for (i=0;i<theform.length;i++){
var tempobj=theform.elements[i]
if(tempobj.type.toLowerCase()=="submit"||tempobj.type.toLowerCase()=="reset")
//disable em
tempobj.disabled=true
}
}
}
