Currently, the local checkout server is set to the Currant Page Submit trigger, Doers this trigger work? If this trigger works than you should use that for the local checkout and Store order Summary behavior.
as for the images, you are using the ADDT Show Dynamic Thumbnail behavior to set the thumbnail name, and this behavior is not in the cart display loop. move the code:
?php
// Show Dynamic Thumbnail
$objDynamicThumb1 = new tNG_DynamicThumbnail("", "KT_thumbnail1");
$objDynamicThumb1->setFolder("shopimages/".$eCart1->DisplayInfo("image"));
$objDynamicThumb1->setRenameRule($eCart1->DisplayInfo("image"));
$objDynamicThumb1->setResize(110, 110, true);
$objDynamicThumb1->setWatermark(false);
?>
to be inside the cart display loop, look for:
<?php
while (!$eCart1->EOF()) {
?>
and pate the Show Dynamic Thumbnail code just after it.
