ACF and Gravity Forms Plugin Integration (Using a for loop)

Question

I'm using Advanced Custom Fields for Wordpress in combination with a plugin that integrates Gravity Forms.

The plugin makes available a gravity_forms function in which to display a specific gravity form to the frontend.

As per the plugin's documentation, I am using a for loop to loop through all gravity forms and display the form selected in the backend on the page.

My code looks as follows:

if( have_rows('content_area') ):
while ( have_rows('content_area') ) : the_row(); 
    if( get_row_layout() == 'gravity_form' ):
        $form = get_sub_field('form'); 
            foreach($forms as $form) {
                gravity_form($form, true, true, false, '', true, 1); 
    }
    endif;
endwhile;
else :
// do nothing
endif;

When I remove the foreach loop and pass a specific form ID into the gravity_form function (instead of the $form variable) it outputs the correct form to the page.

My PHP skills aren't that great so I suspect it is something I am missing that the documentation hasn't included.

Here are some screenshots of my ACF setup.

it may, or may not be worth noting that I also tried with:

$form = get_field('form');

Remove the foreach because the var $forms do not exists, so it can't works.

Try instead :

if( have_rows('content_area') ):
while ( have_rows('content_area') ) : the_row(); 
    if( get_row_layout() == 'gravity_form' ):
       if( get_row_layout() == 'gravity_form' ):
           gravity_form(get_sub_field('form'), true, true, false, '', true, 1); 
       }
    }
    endif;
endwhile;
else :
// do nothing
endif;

EDIT: If you are returning more than one form, you can use the foreach but with the right variable so juste replace $form = get_sub_field('form'); by $forms = get_sub_field('form')
