If you have this line

[set cross_codes][item-data merchandising cross_sell][/set]

in your flypage.html file, you can test it like this

[if !scratch cross_codes]
  no cross codes found
[else]
  cross codes found
[/else]
[/if]

You can, of course, leave out the [else] statement.

You can also check to see if a field in your database has data like this 
(this example assumes you are within a [fly-list][/fly-list] block.

[if-item-data merchandising cross_sell]
  data found
[else]
  no data found
[else]
[/if]

Again, the [else] is optional.
