Problems using "Validate Fields" ...

I'm using the "Validate Fields" in EVENT SUBMIT and it works correctly ...
When I use the "Validate Fields" in another EVENT any does not work ...
Why does it only work on submit?

In Validate Fields "validate_fields39" I ask if "button69" is present ...
We can see in the above arfray that it is NOT present ...
But anyway "validate_fields39" returns with var = 1

Array
(
    [option] => com_chronoforms6
    [cont] => manager
    [chronoform] => defined-3
    [event] => page3
    [cpf] => 40781836700
    [funcao_do_ponto] => 
    [titulo_da_funcao] => 
    [identificao_do_ponto] => 
    [descreva] => 
    [button58] => 
    [nome] => Extrom Technology
    [select39] => 0
    [button44] => 
)

Array
(
    [validate_fields39] => Array
        (
            [log] => Automatic validation enabled.
            [var] => 1
        )

    [validate_fields13] => Array
        (
            [log] => Automatic validation enabled.
            [var] => 
        )

)

Note the "validate_fields13" is defined in the SUBMIT event

Because the field and therefore the rules attached to it only exists in the section that points to the SUBMIT event. If the field doesn't exist in the form and you're only asking it to validate the fields that exist, it will pass.

Ok, I understand the reason, now how to implement a page in "LOAD" and then a second page where a button is "ok" goes to submit, a second button is "next" with the function back to the same second page ?
I already tried "Multi Page" to transfer the same session ... to no success!

Look at multi page demo form

Okay, I've already seen the "https://www.chronoengine.com/faqs/74-chronoforms/chronoforms6/5310-how-to-build-a-multi-page-form" and tested the example however when I try to reload some page of this sequence the Validate_field placed in the submit is not able to verify the certain button to be able to divert through Event_load to any page in the same sequence

Sorry I don't understand.
