How do I actually start the invoke the subprogram node shown in the loop examples?

I have setup the node tree as in the example 1 but don't see the output shown in example 1 (the iterations list).

How do I get the subprogram to actually start so I can see the outputs?

    The Loop Viewer node fills a text block with its values. Did you assign the loop viewer to a text block by either pressing the + in the node or selecting an existing text block by clicking the empty field in the loop viewer? If you did that, can you switch to the Text Editor view (or place them side by side like in the documentation) and check the contents of that text block? – binweg Oct 12 at 6:51
