Hi all,

I'm having hard time to find a solution to my problem.  I've got a
simple table with a dates column where I set an $sdate variable in the
first row.  What I want to achieve is that the dates in the column 4 are
the sum of the date from the row above plus the number of days in column
3 in the same row apart from the field @4$4 which uses the $sdate
variable; thus my naïve column and field formulae:
@4$4=$sdate + $3::$4=@-1$4+$3

#+TBLFM: @4$4=$sdate + $3::$4=@-1$4+$3::@21$3=vsum(@II..@III)::@21$4=@III-1::$sdate=<2013-06-05 Wed>
--8<---------------cut here---------------end--------------->8---

The problem is that when I change the $sdate and recalculate the whole
table with `C-u C-u C-c C-c' only the element @4$4 is set.  It seems
like the column formula doesn't apply to the other fields.

So the question is what am I doing wrongly?  Didn't I get how the column
formula works or is it a problem with the date calculation?

Any help would be very much appreciated,
cheers
