Hi, got this one right thanks to the “hints”, there’s one thing I still don’t understand… how does PHP make the connection between the new variable (\$is_answer_correct) and the values of \$player_one[‘is_correct’ = FALSE] and \$player_two[‘is_correct’ = TRUE]? shouldn’t the variable in the new function markAnswer() match the key ‘is_correct’? And shouldn’t the new variable \$is_answer-correct return ‘undefined’?
thanks.

and here’s my code:

<?php namespace Codecademy; \$learner_one = ["is_correct"=>FALSE, "box"=>["shape"=>"none", "color"=>"none"]]; \$learner_two = ["is_correct"=>TRUE, "box"=>["shape"=>"none", "color"=>"none"]]; function markAnswer(\$is_answer_correct, &\$box) { if (\$is_answer_correct) { \$box['shape'] = "checkmark"; \$box['color'] = "green"; } else { \$box['shape'] = "x"; \$box['color'] = "red"; } } markAnswer(\$learner_one['is_correct'], \$learner_one['box']); markAnswer(\$learner_two['is_correct'], \$learner_two['box']); print_r(\$learner_one['box']); print_r(\$learner_two['box']);

We are just a bit unsure of your question and its context. Plus, we cannot easily read your posted code although that’s secondary. Understanding your question is paramount.
