Hi @karla,
You can do it quite easily by combining the split() function with the get() function. Like this:
I made a dummy variable that holds your text: pureText:

I then split() this, and wrap the split in a get() function, to get the n-th item.

{{get(split(2.pureText; ","); 2)}}
The 2 and 4 in these functions, get the 2nd and 4th item. So you can do that with any number.
You can also wrap the split() in a first() or last() function to get the first and last item:

Result:

Hope that helps!
