Let's open our stack from yesterday:

And copy the GATHER INFO button, and then paste that button into today's stack:

You should now have the GATHER INFO button in a silly place on today's stack.

We need to steal the script from the GATHER INFO button:

Before we paste the script into our GET DATA 2 button we need to prepare for that:

Whenever we start a line with two dashes -- that line does not count as code;
this is useful for separating sections of code and for writing comments.

Now we can paste our copied script between the two lines:

Save your stack.

Now delete the GATHER INFO button that we no longer need.

Now, we need to modify the script of button GET DATA 2:

This is a repeat loop so that each time a new data set is entered
it ends up in a new line in the scrolling list field.The second modification makes sure the data goes into the empty line.

Well, I hope I didn't mislead you too much.  :)

Next weekend I'll start on data-sorting.

OK, Yellowbird, let's take things slowly.

1. What version of the Mac Operating system are you using?

2. Is your problem with downloading LiveCode?

If you can answer those questions first that would be a great help.

Hi Richmond. I have a MacBook Air(13-inch, early 2015) running macOS Catalina version 10.15.Livecode starts to download there is a ? about the amount to be downloaded and it appears to down indefinitely until I finally have to delete. I’m about to give up

I'm sorry I took so long to respond: just had supper after a long, slightly bl**dy day at the chalk face.  :)

That's very queer indeed.

Are you downloading this version?
