figured it out.
you have to have PG in the root of your site
modify the code as indicated in BOTH of the Product_Detail.php files, (one under the root and one under Admin)...modify line 851 of Product_Detail.php in the root, and line 907 of Product_Detail.php under Admin to:
<?php echo wa_evaluate($row_WADAProducts["ProductLongDesc"]); ?></div>
copy the wa_evaluate.php file to both the root directory and to the Admin directory
copy the code from the PG gallery to the long description as instructed and now it works!!
