bbcard random_number token not working?

[Fonzie13]

Trying to get bbcards to show a background image from each player's stadium, and also trying to have multiple image options per team. And I'm getting a weird problem ...

If I use an xml with no random number token - just using one image per team - the file works fine. But if I insert the random number token, there is no background image - the card is transparent behind the player facegen.

I'm not sure what I'm doing wrong, since ...

(1) I'm using the exact same coding model from other bbcards that use multiple images (Topps 1975, Fleer 1960) ... and

(2) On occasion, the random file will actually work ... once. I will get a card with a background image. But then if I re-roll the card generation (because I want to see what the other backgrounds look like), it comes up blank.

If someone wants to take a look at this, and try to figure out what I'm doing wrong, I'd be grateful. Files are in the attached zip. Thanx.

UPDATE: finally figured it out. The [%RANDOM_NUMBER] switch requires TEN files, numbered 0 thru 9. I was only using two or three files.
