Auto Calculate Text Fields?

Hi all,
Suppose I have 3 text fields. I put a number into fields 1 and 2. Without clicking anything, the sum of fields 1 and 2 automatically appear in field 3.
How does one achieve this?
Thanks,
Jon

Such a fun thing.
In the card script:
Code: Select all
on textChanged
put fld 1 + fld 2 into fld 3
end textChanged

Hi again.
Know that you can insert stuff like:
Code: Select all
if the short name of the target is in variableContainingTheCorrectFieldNames and\
target is a number then...
So that only the two fields of interest with valid text place their sums into that third field. That sort of thing, so that it actually works.

I really like that second one Craig
I didn't see anyone checking if the field had a number or if it was empty though, and although you can add, subtract, and multiply with it, you really shouldn't ever divide by 0 if you can avoid it.

...and target is a number...?
Jamais, mes amis, jamais!

Oh, mon dieux, c'est ma faute, très désolé!
I was not aware of the fine difference between "the target" and "target"!
Merci, mon chèr, I learned something new today!

Klaus.
You, know, I thought that was it.
After all these years, you did not know about "target"? It goes back to HC v.1.
It really is a useful gadget. How did you live without it?

I was not "X-Talk ready" when I received my first Mac LC with HC pre-installed in 1993, so I did not really understand HC or dived deeper into it.

This brings up my pet peeve about the omission of "the" before property names. It can bite you if you aren't familiar with the entire dictionary.
