Leo,
I agree with Jim that assigning a field the property "Required" will result
in a message informing the user if that field has been left blank, if and
when the user submits the data to a web server.
But because our forms generally do not submit the data to a web server, I
have written JavaScript to check for blank fields,
As a matter of course, we always include the following buttons (among
others) on our forms: "Save Data", "Print", and "Email Form". Because
these three buttons are the ones that the user might select upon completion
of the form, I place the logic to check for blank fields in the "Mouse Up"
action for these buttons.
Here are two examples:
// This code would be added to a "Print" button created by the forms
designer.
var f1 = this.getField("SSNUM");
var f2 = this.getField("TIMEPM");
if (f1.value == "")
{app.alert("Social Security Number is a required field!")
if (typeof app.formsVersion != "undefined" && app.formsVersion >=
4.0)
// Version specific operation:
f1.setFocus();}
else
{
if (f2.value == "")
{app.alert("Time is a required field!")
if (typeof app.formsVersion != "undefined" &&
app.formsVersion >= 4.0)
// Version specific operation:
f2.setFocus();}
else
app.execMenuItem("Print");
}
Or
// Enumerate through all of the fields in the document.
for (var i = 0; i < this.numFields; i++)
{
var f1 = this.getField(this.getNthFieldName(i));
if (f1.value == "")
{
// app.alert(this.getNthFieldName(i) + " is a required
field!")
// Display the "Short Description" rather than the possibly
cryptic field name.
app.alert(f1.userName + " is a required field!")
if (typeof app.formsVersion != "undefined" &&
app.formsVersion >= 4.0)
// Version specific operation:
f1.setFocus();
}
}

Hello Jim. I wasn't thinking from my standpoint (the creator of the field
fillable form), but from the end user's standpoint. The end user has many
fields to complete and wants to know if he/she has missed completing any
fields.

You don't need the javascript. You only have to check the "Required" check
box when laying out fields.
