Hello,<br><br>I&#39;m trying to provide the ability to upload more than one file in the configuration of one of my custom blocks. <br>I got the basics, but everytime I click on upload button, I get this:<br><br><i>Notice</i>: Undefined index:  uec_core_socials_block_image in <i>uec_core_socials_block_image_validate()<br>

</i><i>Notice</i>: Undefined index: files_fieldset in <i>uec_core_socials_block_image_validate() </i><br><i>
<br></i>I don&#39;t know why I&#39;m getting this because the index is there and works for other blocks I have created that way.<i> </i>I&#39;m also following the ajax_examples module in the examples module.<br><i><br></i>Below is the snippet I&#39;m working with:<br>
