Hallo Michael,

thanks for the pointer to http://orgmode.org/org.html#Formula-syntax-for-Lisp -
it was very helpful for my understanding.

Hm. I still got #ERROR. I reduced my issue to calculate the float (for hours)
without multiplying it with "value":

| time [h:m:s] |   value | product |
|--------------+---------+---------|
|     09:15:00 | 2.54321 | #ERROR  |
#+TBLFM: @2$3='(org-time-string-to-hours $1)
#+TBLFM: @2$3='(org-time-string-to-hours $1);L
#+TBLFM: @2$3='(org-time-string-to-hours "$1");N

... each of the TBLFM results in the same error.

At this stage, $2 is not my problem any more.

Do you have any further idea?
