milogcsetc on "[Plugin: Gravity PDF] Correct syntax for pullingcheck box data?"

I've built a form that allows a user to customize a unit with options that are offered in radio buttons and checkboxes. I'm trying to build a custom-template PDF invoice that checks to see if a given option is selected in its entry, then outputs a table row of condensed information about each option if it was selected.

So far, the form is doing great with radio buttons but I can't get any selected checkboxes to print. Here's my template php, this one is for a single checkbox in Field 109:

<?php if (substr($form_data['field'][109],0,7) == 'APX-AMC') { ?> <tr><td>1</td><td>APX-AMC</td><td>APX Master Clock</td><td>$1750</td><td>$1750</td></tr> <?php }; ?>

In the wp_rg_lead_detail table for my test entry I see that the field_number is 109.1, but adding that to the above doesn't work. What am I doing wrong? I have some fields with multiple checkboxes, so if you could show me that template too, that would be greatly appreciated. Thanks!
