error validating number 4 or 5 digits

I am hoping a javascript guru can help me debug a problem with a validation function.  I have a simple javascript function that validates an input that must be numeric and 4 or 5 digits.  However, it appears to be causing errors.

See below for the validation function.

Thanks for any help.
This code causes errors:

function checkemployeenumber(input) {
        var str=input.value;
        var filter = /^[0-9]{4,5}$/;

        if (filter.test(str)) {
            return true;
        }else{
            return false;
        }
    }

If I change to just validate 5 digits like this it works:

function checkemployeenumber(input) {
        var str=input.value;
        var filter = /^[0-9]{5}$/;

        if (filter.test(str)) {
            return true;
        }else{
            return false;
        }
    }

well that seems to work for me, but you could try

/\d{4,5}/

How are you using the function?

This appears to work just fine...
<html>
<head>
<script type='text/javascript'>
  function check( input ) {
    var str = input.value;
    var filter = /^[0-9]{4,5}$/;
    var result = filter.test( str );
    alert( result );
    return result;
  }
</script>
</head>
<body>
  Number: <input type=text onchange='check(this)'>
</body>
</html>
