In this code you are talking about the NUMBER of the card

>         repeat with cardNo = 1 to 10
>         put id of card cardNo of bg "Background" into thisCard
>         get field 1 of thisCard
here you are using the ID of the card.

Hypercard distinguishes between the ID and the NUMBER.  The number of a 
card is simply where it is compared to the first card of the stack.  As 
you add and delete cards, the number of each card changes.

The ID of a card is a unique number that never changes no matter how other 
parts of the stack are modified.  In general, the ID is a 4 to 5 digit 
number, so 1 to 10 probably don't even exist in your stack (I don't know 
why this is so).  

Generally you use the number of the card to go through a list of cards, 
and the ID to pick out a specific card.  To get your example to work, use:

      repeat with cardNo = 1 to 10
      put NUMBER of card cardNo of bg "Background" into thisCard
      get field 1 of thisCard

The caps in number are for emphasis only.

Happy scripting.
