Hi PDX,
So instead of setting up a unique tracking url what you want to do is go to step 6. Choose your landing page and select you first offer. Add another offer to this page to add a second. Continue to do this until you have all your offers there, then select get landing page codes.
There you will get your java script code and below that you will see a redirect php generated for each of your offers. Now normally with each of those redirect codes you would save them with your text editor, or dream weaver, as redirect1.php, redirect2.php and so on, and upload them to your ftp. then you take your link on your page, "Click here now" and you set that to connect to redirect1.php, and it will connect to your offer fire a pixel and track everything.
