Need validation script to make Submit Form work

You need to add something like this before the block of code you already have:

Thanks! That Worked Great!

Here is the final code. Currently if some required form is missing data it just stops the send email command.

Where, and what code would I put to place a general alert "You cannot submit form until all fields are completed"

//Validate before continuing
if (this.getField("DELIVER_TO").value !=null && this.getField("DELIVER_TO").value!="" && this.getField("PN#1").value !=null && this.getField("PN#1").value!="" && this.getField("DESCRIPTION1").value !=null && this.getField("DESCRIPTION1").value!="" && this.getField("PRICE1").value !=null && this.getField("PRICE1").value!="" &&
this.getField("DATE REQUIRED1").value !=null &&
this.getField("DATE REQUIRED1").value!="" && this.getField("ACCOUNT NUMBER1").value !=null && this.getField("ACCOUNT NUMBER1").value!="")
// change the names of the fields to match your fields...
{
// This is the form return e-mail. Its hardcoded
// so that the form is always returned to the same address
var cToAddr = "nightvision [dot] procurement [at] itt [dot] com";// First, get the client CC e-mail address
var cCCAddr = this.getField("DELIVER_TO").value;

var cSubLine = "NEW PR SUBMITTED ( "
+ this.getField("TOTAL").value + " "
+this.getField("PRODUCT OR SERVICE").value + " "
+ this.getField("REQUEST RECEIVED").value + ")";
var cBody = "Thank you for submitting your form.\n" +
"Save the mail attachment for your own records";

// Send the form data as an FDF attachment on an e-mail
this.mailForm({bUI: true, cTo: cToAddr, cCc: cCCAddr,
cSubject: cSubLine, cMsg: cBody});
}

Add this just after the block of code that sends the email:
