Adding if statement to existing JavaScript code

Brendan,

I would be grateful for some help in adding the right JavaScript to existing code you provided.

I have a several Forms in the same database. The two which are relevant:

A. a Form to record details of documents (Document Form)
B. a Form which lists the names of persons who will sign an individual document (Director Form)

In the Document Form I have created a Link to Form from Document Form to Director Form (One to Many.)

Some documents in the Document Form will be signed and some will not. If the document is signed then I will use Linked to Form field to choose a director from the Director Form.

In the Document Form I have then created:

(a). a further field which with a script (which you provided and I adapted) to extract certain detail from the Director Form (Script Field). See below for the code.

(b). a further field (text) which states the number of directors signing (and is populated by a pick list (eg 1, 2, 3 etc)) (Directors Signing Field)

For example:

1. for one record in Document Form I may have a power of attorney which needs signing and I will add in the Linked to Form field a director (using the tick option, Select existing linked records)
2. for another record in Dcoument Form I may have an official document which does not need signing, and I will not add a director.

The issue is that in the Script Field is as follows:

i. that if the document needs signing, and I will select the director and the Script Field will be populated as expected.

but

ii. that if I create a record in the Document Form where a document does not need signing, I will not add a director in the Linked to Form field, but the Script Field is still filled in (with details not necessarily related).

Is there a way (or what is the code to add to the script) which tests that if the Directors Signing Field is not populated with anything then the Script Field is blank but otherwise the result variable from the script is used?

I know how to create if fields just not with Javascript (despite the sample code you provide).

I guess what I wish to achieve:

If Directors Signing Field is empty then result
otherwise make Script Field blank

Existing code in Script Field

// Get the ID of the Form - click on the Form heading to the left
// Then click on "ID" button on left
// And assign to variable "directors_id"

var directors_id = 'fld-b97b1fadf82f42e08b2f8be84b5a0bb9';

// set list of records to variable "directors_record

var new_identified_work_record = record.getFieldValue(directors_id);
// var directors_record = record.getFieldValue(directors_id);

// Test if there is a record
if (new_identified_work_record.length >0) { 

//Select the first reocrd 
var first_new_identified_work_record = new_identified_work_record[0];

// Assign record to variable
var identification_details_newly_identified_work_address_id = 'fld-cf17026d0c4a46c492195b21ad872a7e';

// var full_address_id = 'fld-9b8f0ecdd8b3422bb1bcbd4b4a9a2077';

// Assign value of reocords to a variable

var address = first_new_identified_work_record.getFieldValue(identification_details_newly_identified_work_address_id);

// Put value of record into a result

result = address	

}

// print out value of result into field
result;
