Strange subroutine error

oh wow, thank you!

I do not need that expanding - I used it for debugging, it is just that it seemed to me that I did not get any lines in preview, so I thought that something was wrong and I tried to find a cause.

As I was writing this, I decided to check once more and now I see lines in the preview. Who knows, maybe some later edits fixed that cause, maybe I just did not notice them.

Anyways, thank you for looking into this!!!
