Hello Kiki,

Please replace the following code with this:

instead of

// Replace this by user level name.
	if ( $level && $level->name = 'gold' ) {
		return true;
	}

use this comparison with level id.

	// Replace this by user level name.
	if ( $level && $level->ID == 1 ) {
		return true;
	}

You can locate Level id using the following screenshot:
