Cross-sell - if downloadable - fails

[matthelm]

Subject says it all. The zen-cart shop I inherited is using the cross-sell module (installed by my predecessor). It seems to work fine for regular products, but if you set up cross-sell on a downloadable product, nothing gives.

Does anyone have a canned fixit available? If not, then any pointers on what pages, queries I should be working?

Thx, Bob

This is taking a lot of digging, several hours of looking through unfamiliar territory, but so far - there is a file called: xsell_products.php. This install is using the one in includes/modules/classic.

For regular, non-downloadable products, the file is called and an sql query is executed which produces an array which results in cross-sell products displaying.

The problem seems to be that this file is not called if the product is downloadable. Any suggestions as to which file(s) i need to check which contain the query to call this file?
