Dynamically Load Select Options from 2 Different Fields

Hi – I’m trying to set up a select field that pulls the options from 2 different fields inside a repeater.

Specifically, when a user sets up a Bout, they will select a fighter for the red corner and the blue corner. After the match is over they are able to select the “winner”. I want the winner select field to pull in the selections from the red corner and blue corner fields (so it would pull in 2 options, but from different fields). I tried editing this sample code, but not even the red corner is showing! How to I get it to load the 2 selections? Thank you in advance for any help!

Fields:
Repeater field name: bouts
Red Corner field name: red_corner
Blue Corner field name: blue_corner
Winner select field name: winner

Here’s the code so far in the functions file:

function acf_load_winner_field_choices( $field ) {
	
	// reset choices
	$field['choices'] = array();
	
	// get the value from bouts without any formatting
	$choices = get_field('red_corner', 'bouts', false);
	
	// explode the value so that each line is a new array piece
	$choices = explode("\n", $choices);

	// remove any unwanted white space
	$choices = array_map('trim', $choices);

	// loop through array and add to field 'choices'
	if( is_array($choices) ) {
		
		foreach( $choices as $choice ) {
			
			$field['choices'][ $choice ] = $choice;
			
		}
		
	}
	

	// return the field
	return $field;
}

add_filter('acf/load_field/name=winner', 'acf_load_winner_field_choices');
