Variable List appearing squashed, what do I do?

I am attempting to add a variable to my app, however, when I try to select one it appears squashed and therefore rendering it unusable. I need a solution soon as this is actually homework for a class I take!

Do you mean this:

just double click on it.

Click and drag; do not double click on the variable.

In the Blocks Editor, pull out your PC keyboard and start to type
init global
then drag the new init global variable into the workspace and overtype its name to something appropriate, like questionList.

What does '"squashed" mean?
