I need a code example of a Javascript function that will test for a number range that can include whole numbers and decimals. I am not a Javascript programmer but I do have a function that was written for me that is part of this validation that I am including as an example. This validation is made against several functions. Here is the example that has nothing to do with a number range:

function validInt(formField,fieldLabel,required)
{
    var result = true;

    if (required && !validRequired(formField,fieldLabel))
        result = false;

     if (result)
     {
         var num = parseInt(formField.value);
         if (isNaN(num))
         {
             alert('Please enter a number for the "' + fieldLabel +'" field.');
            formField.focus();
            result = false;
        }
    }

    return result;
}

not use some Regular Expressions to do this for you ? (see http://builder.com.com/5100-6371-1049625.html)
