"Hi Larry, \nMy continued question on Error message in Browse.php \n  \nThanks for your reply.  I've been trying to make browse.php happen these days. \n  \nFollowing you advice, I put the four values of variables below before the script line: \n  \n$type = \"coffee\"; \n$sp_type = \"coffee\"; \n$category = 'coffee'; \n$sp_cat = 'coffee'; \necho $type;  \necho $sp_type; \necho $sp_cat; \necho $category; \n  \nThen the message reads in the browser: \ncoffee \nUnfortunately there are no products to list in this category. Please use the links at the top of the page to continue shopping. We apologize for the inconvenience.  \n  \nAre the variables functional in browse.php?  If not, what else shall i try to debug next? \nThanks for your time. \n"
