Re: [Orgmode] I do not understand this error

[Cecil Westerhof]

I have been experimenting a little bit more. I now have the following
table:
        
|---+------------+---------------+---------------+-----------------------+----------+-------|
        |   |       date | previous date | prev  at once | prev with dummy 
field | row date | dagen |
        
|---+------------+---------------+---------------+-----------------------+----------+-------|
        | # |            |               | filled        | empty                
 | EMPTY    |       |
        | # | 2007-07-09 |               | filled        | empty                
 | FILLED   |    -3 |
        | # | 2007-09-11 |    2007-07-09 | filled        | filled               
 | FILLED   |    64 |
        | # |            |    2007-09-11 | filled        | filled               
 | EMPTY    |       |
        | # | 2006-12-31 |               | filled        | empty                
 | FILLED   |  -193 |
        
|---+------------+---------------+---------------+-----------------------+----------+-------|
        #+TBLFM: $3='(concat @-1$2);S::$4='(if (not (equal (concat @-1$2) "")) 
"filled" "empty")::$5='(if (not (equal (concat $3   ) "")) "filled" 
"empty")::$6='(if (not (equal (concat $2   ) "")) "filled" "empty")::$7='(if 
(and (not (check-if-after-hline)) (not (equal @-1$2 "")) (not (equal $2 ""))) 
(-  (time-to-days (org-read-date t t (concat $2))) (time-to-days (org-read-date 
t t (concat @-1$2)))) "");S
        

When checking for the previous date at once you always get filled. If
the previous date is copied to a field and this field is checked, you
get the expected value.
What is happening here?

Also why is in the column 'row date' everything in caps?
