Post edit issue

Hello,

I use Gravity Forms with Oxygen Builder. I had no worries but now I have a worries. Here I have a loop with posts (custom post Flash), I created a form that changes the taxonomy of the form to put it in the trash. So there is a “Flash ID” field: I get the ID of the post in question “add_filter( ‘gform_field_value_Flash_ID’, ‘get_Flash_ID’);
function get_Flash_ID( $value ) {
return $postid=get_the_ID();
}”
When my field is not hidden the ID of the post is the correct one, in my entries it gets the correct ID in the field “Flash_ID” but it applies the modification in the page where there is my loop and not in the ID I have recovered, yet in ACF Target ID I put {Flash_ID:5}

I don’t know where the problem comes from, can you help me?

Thank you!
