Creating an If/Else statement using WPAlchemy MetaBox radio boxs

Question

I am using the WPAlchemy MetaBox Class to create additional metaboxs on my site. One has a section with a group of radio boxes. I've coded it as follows:

    <?php $mb->the_field('docposs'); ?>
    <input type="radio" name="<?php $mb->the_name(); ?>" value="yes"<?php $mb->the_radio_state('yes')?' checked="checked"':''; ?>/>Yes
    <input type="radio" name="<?php $mb->the_name(); ?>" value="no"<?php $mb->the_radio_state('no')?' checked="checked"':''; ?>/>No
    <input type="radio" name="<?php $mb->the_name(); ?>" value="unknown"<?php $mb->the_radio_state('unknown')?' checked="checked"':''; ?> />Unknown

What I would like to be able to do in my template is echo a string based on which box returns checked, something like:

if (checkbox == yes) {
    echo "If you wish to make";
} elseif (checkbox == no) {
    echo "an apple pie from scratch,";
} else {
    echo "you must first invent the universe";
}

But I cant make it work :(

This (and many ridiculous variations on this) just returns 'yes' instead of the echo.

if ($provenance_mb->the_value('docposs') == yes) {
 echo 'hello world';
}

Any help would be appreciated.

not sure what you are doing wrong, your code looks ok at first glance ... make sure you represent yes and no as string values ...

if ( 'yes' == $provenance_mb->get_the_value( 'docposs' ) ) {
    echo "If you wish to make";
} else if ( 'no' == $provenance_mb->get_the_value( 'docposs' ) ) {
    echo "an apple pie from scratch,";
} else {
    echo "you must first invent the universe";
}
