Two questions about your code:

1. I see you name some of your calculation variables with a leading tilde, e.g. `~rep` Any reason for this?
2. These lines intrigue me:

```auto
~rep = Code(Get(WindowName))
$$Activity[~rep] = ...

```

It looks like you are taking the name of the window, and converting that to an integer, and then using a repeating field $$Activity[] to store the data for that specific window.

Is this safe, however? If the Window name is long, then you'll end up with a ridiculously long integer:

My assumption would be that $$Activity[a very long integer] would lead to out of memory errors as FileMaker attempts to allocate a gigantic array. Perhaps that's not what FileMaker does for repeating fields or variables?
