Report preview looks OK but CSV file save is rows of "","","",""

I've done very little report programming so I'm puzzled with this one.

Figure 1. Data shows up in the Report Designer Preview.

Figure 2. The schedule configuration.

(A manual Execute report button would be really handy!)

The file is created with 118,000 lines all of which are,

"","","",""
"","","",""
"","","",""
"","","",""

Has anyone any suggestions?
Many thanks.

Code your own CSV conversion without using Reporting?

{ Not quite kidding. I don't ever use the CSVs from Reporting. }

I don't use the csv file save either, but when i tested it seemed to work as intended. Your report design might be the culprit. The manual execute button is right here:

Gee, the tooltip even spells it out. Thanks!
