Pre-populate multiselect fields in different forms

I have two gravity forms which are used on different pages of my site. Both have multi-select fields which I want to pre-populate with a list of custom post titles.

On one form, the pre-populate script works great, but on the second it doesn’t work no matter what I try. What am I missing?

Here’s the code for the filters I have on my functions page in my theme:

++++++++++++
// prepopulate gform

add_filter( ‘gform_pre_render_12’, ‘populate_posts’ );
add_filter( ‘gform_pre_validation_12’, ‘populate_posts’ );
add_filter( ‘gform_pre_submission_filter_12’, ‘populate_posts’ );
add_filter( ‘gform_admin_pre_render_12’, ‘populate_posts’ );
function populate_posts( $form ) {

foreach ( $form['fields'] as &$field ) {

    if ( $field->type != 'multiselect' || strpos( $field->cssClass, 'populate-posts' ) === false ) {
        continue;
    }

    // you can add additional parameters here to alter the posts that are retrieved
    // more info: http://codex.wordpress.org/Template_Tags/get_posts
    $args = array(

‘numberposts’ => -1,
‘posts_per_page’ => -1,
‘post_type’ => ‘na_jobs’
);
$posts = get_posts( $args );

    $choices = array();

    foreach ( $posts as $post ) {
        $choices[] = array( 'text' => $post->post_title, 'value' => $post->post_title );
    }

    // update 'Select a Post' to whatever you'd like the instructive option to be
    $field->placeholder = 'Select a Job ID#';
    $field->choices = $choices;

}

return $form;

}
// prepopulate gform

add_filter( ‘gform_pre_render_13’, ‘populate_posts’ );
add_filter( ‘gform_pre_validation_13’, ‘populate_posts’ );
add_filter( ‘gform_pre_submission_filter_13’, ‘populate_posts’ );
add_filter( ‘gform_admin_pre_render_13’, ‘populate_posts’ );
function populate_posts_applicants( $form ) {

foreach ( $form['fields'] as &$field ) {

    if ( $field->type != 'multiselect' || strpos( $field->cssClass, 'populate-posts' ) === false ) {
        continue;
    }

    // you can add additional parameters here to alter the posts that are retrieved
    // more info: http://codex.wordpress.org/Template_Tags/get_posts
    $args = array(

‘numberposts’ => -1,
‘posts_per_page’ => -1,
‘post_type’ => ‘applicants’
);
$posts = get_posts( $args );

    $choices = array();

    foreach ( $posts as $post ) {
        $choices[] = array( 'text' => $post->post_title, 'value' => $post->post_title );
    }

    // update 'Select a Post' to whatever you'd like the instructive option to be
    $field->placeholder = 'Select an Applicant ID#';
    $field->choices = $choices;

}

return $form;

}
++++++++++++

For the moment I disabled the multiselect on this form until I can figure out the issue.
