Summary: problem with HC go to card command

It sounds like Chuq could use a field in each card or background with 
the first line holding the number of linked cards and the names or 
id numbers of the linked cards in the following lines of the field,
but this brings up a problem that I've been having:

I'm trying to go to cards by a name composed of a string constant
and a variable number, as in

  go to card "Sheetnum"&snum    -- and variants, incl. putting "x"&y in parens

but Hypercard usually fails to go to the proper, or any, card.
This occurs only (or primarily) in scripts; if I execute the same
line in the message window, Hypercard takes me to the proper card
without complaining.  Have I overlooked some requirement of the
go command, or can anyone suggest some other likely oversight on my 
part?
