Fixed!
Thanks Ray - you nailed it . . . the include was not added to the page by the ECart wizard. FYI - this is the second cart I have this issue with - this will no doubt fix the other cart as well. Now that I know what to look for; I'll never ask this question again . . . HOWEVER . . . I'm not sure if it's an issue with the wizard of something I'm doing wrong.
Whichever it is, here's a summary (just so you can see all the code from the top of the page):
The original code was:
1 <?php require_once('../Connections/connSpark.php'); ?>
2 <?php
3 $shopBag->GetContent();
4 ?>
When I changed it the code below - it worked like a charm! Thanks again!
1 <?php require_once('../Connections/connSpark.php'); ?>
2 <?php
3 //WA eCart Include
4 require_once("../WA_eCart/shopBag_PHP.php");
5 ?>
6 <?php
7 $shopBag->GetContent();
8 ?>
