X-Cart forums - Froogle feed help

I took Joshuas generous froogle code and modified it for 3.4.3 which I just upgraded , having a prob witht he product_url in the csv strip.

Code is below

Code:

{* HEADER FOR GOOGLE FEED By Joshua Sowin*} 

{* If you remove these headers or change them you do not have permission to use this code. This code is copyright 2003 Joshua Sowin www.gracehost.net *} 

{strip} 

product_url{$delimiter} 

name{$delimiter} 

description{$delimiter} 

price{$delimiter} 

image_url{$delimiter} 

category{$delimiter} 

offer_id{$delimiter} 

ISBN

{/strip} 

{* END HEADER *} 

{section name=prod_num loop=$products} 

{strip} 

http://www.123computerbooks.com/xcart/customer/product.php?productid={$products[prod_num].productid|replace:"\"":""}&cat={$products[prod_num].categoryid|replace:"\"":""}&partner=froogle{$delimiter} 

{$products[prod_num].product|replace:"\"":""}{$delimiter} 

{$products[prod_num].fulldescr|replace:"\r":" "|replace:"\n":" "|replace:"\t":" "|replace:"\"":""|replace:",":","|strip_tags}{$delimiter} 

{$products[prod_num].price|replace:"\"":""}{$delimiter} 

{$products[prod_num].thumbnail|replace:"\"":""}{$delimiter} 

{$products[prod_num].category|replace:"/":" > "|replace:"\"":""}{$delimiter} 

{$products[prod_num].productcode|replace:"\"":""}{$delimiter}{$products[prod_num].param00|replace:"\"":""}{$delimiter} 

{/strip} 

{/section}

In excel the output is this

http://www.123computerbooks.com/xcart/customer/product.php?productid=&cat=&partner=froogle

the productid= isnt being stripped any ideas? it should be stripped like this

http://www.123computerbooks.com/xcart/customer/product.php?productid="missing this number"&cat=&partner=froogle
