Dereferencing control ids

[dunbarx at aol.com]

Pete.


How are you selecting? I made a few controls, and did this in a button:




on mouseUp
   select control 1 and  control 1 and control 3
   repeat for each line rLine in the selectedObjects
         put the topLeft of rLine & return after sLocations
   end repeat
   answer sLocations
end mouseUp


No problems. When I first read your post I thought maybe a "do" construction might be in order, but it works just fine as is.

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?
