Dereferencing control ids

[Scott Rossi]

Hi Pete:

Not sure if this will help but try putting the selObj into a variable first and working with that.

FWIW, I've often gotten mixed results or errors when trying to work with the selObj directly (unless simply trying to check its contents) and placing its contents into a variable has been more reliable for me (YMMV).

Getting a problem trying to grab the topLeft of each control in the
selectedObjects.  Code is as follows:

repeat for each line rLine in the selectedObjects
   put the topLeft of rLine & return after sLocations
end repeat

I get a runtime error on the "put" statement:

(Chunk: error in object expression) near "field id 1004 of card id 1002 of
stack "test"", char 23.

The field reference is what's in rLine.

I've also tried using a do statement resulting in a slightly different
error - "error in source expression"

If I enter - put the topleft of field id 1004 of card id 1002 of stack
"test" - into the message box, I get a valid result.

I have a horrible feeling this is going to be something really obvious but
nevertheless, what am I doing wrong?
