Accessing non-array text inside brackets

I’ve got a quandary. Retrieving a piece of text from a datasource presents it inside brackets.

If you look at the formula for the Alert (which functioned identically when it was set up as an “output of a different node” and not a formula), the example at the right gives the expected result:

…but when I execute the alert, it responds with the results like this:

…and so, the rest of my nodes can’t see it, because it’s expecting just simply text. How can I drill down and just see the text (“Very Hard” in this instance)?
