Hi,
I have been writing in hyperTalk for a while, and there is a problem I
have run into several times.  When I try to run scripts that contain
if statements with this format:

	on mouseUp
  	  repeat with i = 1 to the number of cards
    	    if field 1 of cd i contains "RTFM" then
      	      foobar
    	    end if
  	  end repeat
	end mouseUp

	-- where foobar is any command or set of commands

I get an error message that says "No such card".  The problem is fixed if 
I write the script:

	on mouseUp
    	  repeat with i = 1 to the number of cards
	    get field 1 of cd i
            if it contains "RTFM" then
	      foobar
	    end if
	  end repeat
	end mouseUp

or like this:

        on mouseUp
          repeat with i = 1 to the number of cards
            go cd i
            if field 1 contains "RTFM" then
              foobar
            end if
          end repeat
        end mouseUp

The second correction takes longer to run than the first, but I think
the original script would run even faster, if it worked (one less line).
Am I missing something completely, or is this a problem with HC?
Has anyone else run into this problem?

Thanks for any help.
