Adding more info to Geo Directory Claim Listing Popup

I wanted to add a link to a page that gave more details on the membership options they were choosing from and details of what will happen after they claim their listing.
This is how I did it.

Edit geodir_claim_functions.php in /wp-content/plugins/geodir_claim_listing

Around line 1295, before

<div id="gd_claim_pkgs" class="row clearfix gd-claim-pkgs gd-chosen-outer">
                <label><?php _e( 'Select Package', 'geodirclaim' );?> : <span>*</span></label>
                <select name="geodir_claim_pkg" id="geodir_claim_pkg" field_type="select" class="is_required chosen_select">
                <?php foreach ( $package_list as $package ) { ?>
                <option value="<?php echo $package->pid; ?>"><?php echo stripslashes_deep( $package->title_desc ); ?></option>
                <?php } ?>
                </select>
            </div>

add the following link

<div>
                <h4>Available Packages</h4>

                <a href="http://directory.healingsouls.com.au/claim-listing-membership-options/" class="fancybox iframe" target="_blank"  rel="attachment wp-att-362">
                <p>Click for more details and how your claim is processed</p>
                <img src="http://directory.healingsouls.com.au/wp-content/uploads/2016/04/Prices-image-1-300x191.png" alt="Prices image" width="200" height="auto" class=" aligncenter size-medium wp-image-362" /></a>
            </div>
