Use one field to validate values in one of two fields

Meredith

I am using a script to validate a form using the presence of a value in
one field and determine if there is a value in one of two fields. It
is an either/or situation. If the date rcvd field is not "", then
either the ref names has to be filled in OR the res date has to be
filled in. I have tried many combinations of this. Any suggestions
will be greatly appreciated.

<script language="JavaS cript">
function ValidateForm(){

var Rcv1Field = document.form1. DateRcvd
var Refer1Field = document.form1. RefNames
var FRDfield = document.form1. ResDate

if (Rcv1Field.valu e != "" && (Refer1Field.va lue == "" || FRDfield.value
!= "")){

if (Rcv1Field.valu e != "" && Refer1Field.val ue == "" ){
alert("Please Enter a Referral")
Refer1Field.foc us()
return false
}
if (Rcv1Field.valu e != "" && FRDfield.value != ""){
alert("Please Enter a Final Resolution Date")
FRDfield.focus( )
return false
}
}
return true
}
</script>

Does this do what you want? It requires the Date Received field to be
filled in.

Thank you for your assistance....I was able to use the logic of the
suggestion to get the desired result. This is the snippet that I used:

if (Rcv1Field.valu e != ""){
if (Refer1Field.va lue == "" && FRDfield.value == ""){
alert("Please Enter a Referral Name OR a Resolution Date");
Refer1Field.foc us();
return false;
}
}

The Date Rcvd field is not required, however, if it does have a date in
it, either the referral name or resolution date needs to have a value.
Thanks again.
