i am trying to limit a Gravity Form in my WordPress project by a custom field.
This field, which is an ACF field like others on the same page, only calls a number. I am trying to overwrite the field "limitEntriesCount" which is a gravity-forms setting in the form itself.

I have tried the following code, with some help of a member of Gravity Forms:

    // Change limit entries by custom field.
    add_filter( 'gform_pre_render_1', 'set_entry_limit' );
    add_filter( 'gform_pre_validation_1', 'set_entry_limit' );
    add_filter( 'gform_pre_submission_filter_1', 'set_entry_limit' );
    add_filter( 'gform_admin_pre_render_1', 'set_entry_limit' );

    function set_entry_limit( $form ) {
      $eventTickets = get_field('event_tickets');
        global $post;
        // modify the form object here
        $limit = $post->$eventTickets;
        $form['limitEntries'] = 1; // set to true
        $form['limitEntriesCount'] = $limit;
        return $form;

But it's just not working. I was hoping one of you guys have done this before and could help me out.

Thanks in advance!
