Revised revision . . .
Apparently I'm an idiot . . .
I'm backtracking the page builds via WA eCommerce Recipes360 & there's some basic info that's missing from my code ie: eCart etc. can't insert user-defined info if there's no place to "put it".
Stay tuned . . .
P.S. Is there an effort being made to update the PHP Recipes (eCommerce Recipes360)? The screen shots of "existing" menus, etc. & some of the explanations/directions are inaccurate. eg. page 22:
"In the dialog box, make sure that the Cart name list is set to shoeCart and, from the Payment gateway list, choose PayPal with Line Items – Hidden. Click OK when you're done."
