Thanks for all of your kind replies and suggestions.
First, it's a Yahoo! store and second, I use Win XP Pro & IE6.0 sp2 (the shredder) and I wasn't seeing the code, for whatever the reason? (lot of possible variables there)
I finally got the company I was affiliating to, on the phone after 3 days and they said they were clicking on my links and the ID was displaying fine on their PC.
At this point the conversation took a turn for the worse and they had the b***s to say my links were no good and they wanted all of my images and text descriptions to link to their buy pages for the identical products. 556 links to be modified!
I politely said "I'll get started on my links right away." And I did - I took down the 12 trial links I was using, off the site and deleted my account with them.
The site makes enough money as it is, to keep it in business and in the interim, another distributor of many similar products that I don't carry, gave me 8 new product lines to affiliate with, at 3 x's the commission to boot.
All I have to do is create a new section and upload the the 8 logos of their product lines, (which are well known and different from mine) and write a brief pre-sell sentance or two under each image with my affiliate link in the text. It'll take about 1 1/2 hours to fully complete and optimize the one new section page and will only contain 8 OB affiliate links.
This'll be much better - similar products, made by different companies and at a wide spread in pricing, for my customers to pick and choose what's right for their wallet.
