but how sweet that 15th time can be.

You just need a simple piece of JavaScript depending on what you want to validate, if you wanted someone to enter number chars only for example :

Code: 
<script
  language=&quot;JavaScript&quot;
  type=&quot;text/JavaScript&quot;
>
<!--
    function formVal (form, elmt) {
        var valid = &quot; 0123456789&quot;;
        var rtn = true;
        var temp;
        for (var i = 0; i < form[elmt].value.length; i++) {
            temp = form[elmt].value.toLowerCase().substring (i, i+1);
            if (valid.indexOf (temp) == -1) {
                rtn = false;
            }
        }
        if (rtn == false) {
            alert (&quot;Please enter numbers only&quot;);
            form[elmt].focus ();
        }
        return rtn;
    }
//-->
</script>

<form
  action=&quot;page.asp&quot;
  onsubmit=&quot;return formVal (this, 'username');&quot;
>
  Username: <input
    type=&quot;text&quot;
    name=&quot;username&quot;
  ><br />
  Password: <input
    type=&quot;password&quot;
    name=&quot;password&quot;
  ><br />
  <input
    type=&quot;submit&quot;
    value=&quot;Log In&quot;
  >
</form>

If you want more advice explain what you want to validate Regards

awesome job on the code bigbaddave.
I would recommend doing this also for the phone and fax #'s
if (valid.indexOf (temp) == -1) {
alert (&quot;Please enter numbers only for field: &quot; + elmt.name);
} else { if (valid.indexOf (temp) < 7) {

7 being the minimum amount to make a valid phone #

I may not get it the 1st or 2nd time,
but how sweet that 15th time can be.

forgot to include the alert and another } at the end. don't forget that
if (valid.indexOf (temp) == -1) {
alert (&quot;Please enter numbers only for field: &quot; + elmt.name);
} else { if (valid.indexOf (temp) < 7) {
alert (&quot;Please enter a valid phone number!&quot;)
elmt.focus ();
return false;
}
}
}
}
}
return true;
}
//-->
</script> I may not get it the 1st or 2nd time,
but how sweet that 15th time can be.

once again I fall over my fingures. this will work I swear
if (elmt.name == &quot;PhoneNumber&quot; ||elmt.name == &quot;FaxNumber&quot;) {
for (var i = 0; i < elmt.value.length; i++) {
temp = elmt.value.toLowerCase().substring (i, i+1);
if (valid.indexOf (temp) == -1) {
alert (&quot;Please enter numbers only for field: &quot; + elmt.name);
elmt.focus (valid.indexOf (temp) == -1);
return false;
} else { if (elmt.value.length < 7) {
alert (&quot;Please enter a valid &quot; + elmt.name + &quot;!&quot;)
elmt.focus ();
return false;
}
}
}
}
I may not get it the 1st or 2nd time,
but how sweet that 15th time can be.

Hi David & 'Onpt'

Thanks to both of you for your help!

You have indicated above validating the telephone number and fax number. But, I would also like to validate and FORCE (mandatory) the user to fill out CompanyName, email, LastName and FirstName field as well.

Thanks.

Those are pointed out in David's script with the validation of
if null or &quot;&quot; alert them
copy his code and if you want the phone number length validation I suggested you can place that in there also I may not get it the 1st or 2nd time,
but how sweet that 15th time can be.

Hi,

I have the following fields in the code above:

the telephone number and fax number (validate for numbers)

CompanyName, email, LastName and FirstName (validate to force the user to fill these fields out and validate if the email ends with @)

I think the reason the code you suggested above didn't work is that there no validation being done in submit button, OnClick() or something to that extent?

Again thanks very much for your input!!!
