e.g., In looking at ecommerce stats for a custom variables report, I only want to see numbers for visitors who visited our shipping rates page (zip_check.php).
I don't see anything in "advanced segments" that will help.
I've also tried "filters" in "custom reporting". The most hopeful filter fields I saw were "Page" and "Page Title", but it's unclear to me what these filter do. They don't appear to simply filter for sessions or visits that contain a visit to a particular page.
Here's a report snippet after applying a "Page Title" filter. The numbers obviously got wacky.
UPDATE: Here's a complete snapshot of the report after using "Customize" to filter for "Page Title" exact= "Shipping Calculator".
