Hi,
I have a date field called "Date" and another date field called "Archive".
I would like archive to contain "21/12/Year of field date".
So i tried many things but i still have the same problem. No matter if a use a calculated default value or a rule to update my field archive, i always have the field underline like if the value wasn't matching with the expected field type ...
The formula is : concat("31/12/"; sous-chaîne(Date; 1; 4))
-> displays 31/12/2014 but with the field highlight
I tried all these combinations but none of them worked
concat(sous-chaîne(Date; 1; 4); "-12-31")
concat(sous-chaîne(Date; 1; 4); "-31-12")
concat(sous-chaîne(Date; 1; 4); "/12/31")
concat(sous-chaîne(Date; 1; 4); "/31/12")
concat("31/12/"; sous-chaîne(Date; 1; 4))
concat("31-12-"; sous-chaîne(Date; 1; 4))
I don't get it...
If i pick up the value in the picker it will display the same value but without error message !

Any idea of what's wrong ?
Regards
