Hello,
the output of your choice is stored in the variable set on the region placeholder (in your case, c_expo)
You can choose the output values in a range of options depending on your needs (righ click and choose "Settings" from context menu or double-click on the region, then set an output option).
To get directly the value, in your example you have to choose "nth element in the row" and then the 2nd column.
