How to show/hide a field based on another field.

[jaspert92510366]

I have the following document level script:

function Openn(){
        if(this.getField("cobuyer").value.length == 0)
        {
           this.getField("xcobuy").display = display.hidden;
        }

     else
        {
            this.getField("xcobuy").display = display.visible;
        }

                }
Openn();

I am getting the following error:

Acrobat EScript Built-in Functions Version 10.0
Acrobat SOAP 10.0

TypeError: this.getField("xcobuy") is null
9:Document-Level:Openn

The form is being produced with the data already in it and that field is not null

Thanks

That means the field name you entered is incorrect. Make sure you spell it EXACTLY as it appears on the page, including lower/upper-case letters.

Thanks for the reply.

I copied/paste the name of the field.  It is exactly what is on the form.

Thanks,

Is it possible that I may need to add a delay to the routine?

Shouldn't be necessary... Can you share the file with us (via Dropbox, Google Drive, Adobe Send & Track, etc.)?

Works fine for me... However, there's no need to use a doc-level script for it. You can use the Validation script of the "cobuyer" field, instead. That way it will also work if someone changes the field's value after opening the file. Use this code:

if (event.value.length == 0) {

    this.getField("xcobuy").display = display.hidden;

} else {

    this.getField("xcobuy").display = display.visible;

}
