I have a table that I am display in a website and I want to validate an Input select List for any new records from now on. I don't want validating to issue an error on older records. I am try to find a way to validate without having to use date.

Here is the validation I have for my input selection list:

if(document.getElementById('islTransferType').selectedIndex == 0)
{
alert("Mandatory: Please select Transfer Type for the BatchId your on.");
return false;
}
return true;
}

Please help me as I need it for my job.
